Re: [mkgmap-dev] Commit r3968: merge the optimize-index branch. This fixes some problems with address search
Hi Gerd, I have been testing the new features, and I have some suggestions for the sample file: 1) Spellcheck and new prefixes "Alameda"(means promenade) and "Beco"(means alley): -# portugese -prefix1:pt = "Rua", "Avenida", "Travessa" +# portuguese +prefix1:pt = "Rua", "Avenida", "Travessa", "Alameda", "Beco" prefix2:pt = "da ", "do ", "de ", "das ", "dos " 2) Add Brazil to the Portuguese speaking countries: +lang:BRA = pt lang:CAN = en, fr Best regards, Alexandre On 02/06/2017 02:07, svn commit wrote:

merge the optimize-index branch. This fixes some problems with address search and adds new options which give control the content of the index. Also, option split-name-index is no longer temporary.
New options: --road-name-config=file This option handles the problem that some countries have road names which often start or end with very similar words, e.g. in France the first word is very often 'Rue', often followed by a preposition like 'de la' or 'des'. This leads to rather long road names like 'Rue de la Concorde' where only the word 'Concorde' is really interesting. In the USA, you often have names like 'West Main Street' where only the word 'Main' is important. Garmin software has some tricks to handle this problem. It allows to use special characters in the road labels which mark the beginning and end of the important part. In combinarion with option split-name-index only the words in the important part are indexed.
There are two different visiual effects of this option: - On the PC, when zooming out, the name 'Rue de la Concorde' is only rendered as 'Concorde'. - The index for road names only contains the important part of the name. You can search for road name Conc to find road names like 'Rue de la Concorde'. One problem: Search for 'Rue' will not list 'Rue de la Concorde' or 'Rue du Moulin'. It may list 'Rueben Brookins Road' if that is in the map. Only MapSource shows a corresponding hint.
Another effect is that the index is smaller. The option specifies the path to a file which gives the details. See comments in the sample roadNameConfig.txt for further details.
--mdr7-excl This option allows to specify words which should not be in the road index. It was added before option road-name-config and is probably no longer needed. Example usage: --x-mdr7-excl="Road, Street, Straße, Weg"
--mdr7-del Use this option if your style adds strings to the labels of roads which you want to see in the map but which should not appear in the result list of a road name / address search. The list is used like this: For each road label mkgmap searches the last blank. If one is found, it checks if the word after it appears in the given list. If so, the word is removed and the search is repeated. The remaining string is used to create the index. Example: Assume your style adds surface attributes like 'pav.' or 'unp.' to a road label. You can use --mdr7-del="pav.,unp." to remove these apendixes from the index.
--poi-excl-index By default, mkgmap indexes the following POI types with a non-empty label: - 0x00 .. 0x0f (cities, sub type 0, type <= 0xf) - 0x2axx..0x30xx (Food & Drink, Lodging, ...) - 0x28xx (no category ?) - 0x64xx .. 0x66xx (attractions) This option allows to exclude POI types from the index. The exclueded types are not indexed, but may still be searchable on a device as some devices seem to ignore most of the index, e.g. an Oregon 600 with firmware 5.00 only seems to use it for city search. If you device finds a POI name like 'Planet' when you search for 'Net' it doesn't use the index because the index created by mkgmap cannot help for that search. So, this option may help when you care about the size of the index or the memory that is needed to calculate it. The option expects a comma separated list of types or type ranges. A range is given with from-type-to-type, e.g. 0x6400-0x6405. First and last type are both excluded.A range can span multiple types, e.g. 0x6400-0x661f. Examples for usage: - Assume your style adds a POI with type 0x2800 for each addr:housenumber. It is not useful to index those numbers, so you can use --poi-excl-index=0x2800 to exclude this. - For the mentioned Oregon you may use --poi-excl-index=0x2a00-0x661f to reduce the index size.

First of all, a great thanks to Gerd for the lot of work behind this improvement to search functionality in mkgmap. That said, I think is would be convenient to keep the capability to search the original full name of roads when using road-name-config option, as many users tend to search it instead of main part of the name. Original Garmin maps are able to search both full name and main part. Attached is a first revision of roadNameConfig file which includes all Spanish speaking countries, suggestions from Stéphane and some alphabetical sorting.

Hi Carlos, I am not sure how a search for full name can work in combination with this feature. Maybe by adding the label to MDR15 two times, once with and once without the separator characters. I've no spare time for coding during the next weeks, so maybe someone else can have a look.

Hi,
For France I suggest:
-prefix1:fr = "Allée", "Chemin", "Avenue", "Rue", "Place" +prefix1:fr = "Allée", "Chemin", "Avenue", "Rue", "Place", "Boulevard", "Route"
For Guyana, is a new item necessary ? +lang:GUY = en
Best regards.

Hi Gerd,
I have been testing the new features, and I have some suggestions for the sample file:
1) Spellcheck and new prefixes "Alameda"(means promenade) and "Beco"(means alley):
-# portugese -prefix1:pt = "Rua", "Avenida", "Travessa" +# portuguese +prefix1:pt = "Rua", "Avenida", "Travessa", "Alameda", "Beco" prefix2:pt = "da ", "do ", "de ", "das ", "dos "
2) Add Brazil to the Portuguese speaking countries:
+lang:BRA = pt lang:CAN = en, fr
Best regards,
Alexandre

merge the optimize-index branch. This fixes some problems with address search and adds new options which give control the content of the index. Also, option split-name-index is no longer temporary.
New options: --road-name-config=file This option handles the problem that some countries have road names which often start or end with very similar words, e.g. in France the first word is very often 'Rue', often followed by a preposition like 'de la' or 'des'. This leads to rather long road names like 'Rue de la Concorde' where only the word 'Concorde' is really interesting. In the USA, you often have names like 'West Main Street' where only the word 'Main' is important. Garmin software has some tricks to handle this problem. It allows to use special characters in the road labels which mark the beginning and end of the important part. In combinarion with option split-name-index only the words in the important part are indexed.
There are two different visiual effects of this option: - On the PC, when zooming out, the name 'Rue de la Concorde' is only rendered as 'Concorde'. - The index for road names only contains the important part of the name. You can search for road name Conc to find road names like 'Rue de la Concorde'. One problem: Search for 'Rue' will not list 'Rue de la Concorde' or 'Rue du Moulin'. It may list 'Rueben Brookins Road' if that is in the map. Only MapSource shows a corresponding hint.
Another effect is that the index is smaller. The option specifies the path to a file which gives the details. See comments in the sample roadNameConfig.txt for further details. --mdr7-excl This option allows to specify words which should not be in the road index. It was added before option road-name-config and is probably no longer needed. Example usage: --x-mdr7-excl="Road, Street, Straße, Weg" --mdr7-del Use this option if your style adds strings to the labels of roads which you want to see in the map but which should not appear in the result list of a road name / address search. The list is used like this: For each road label mkgmap searches the last blank. If one is found, it checks if the word after it appears in the given list. If so, the word is removed and the search is repeated. The remaining string is used to create the index. Example: Assume your style adds surface attributes like 'pav.' or 'unp.' to a road label. You can use --mdr7-del="pav.,unp." to remove these apendixes from the index.
--poi-excl-index By default, mkgmap indexes the following POI types with a non-empty label: - 0x00 .. 0x0f (cities, sub type 0, type <= 0xf) - 0x2axx..0x30xx (Food & Drink, Lodging, ...) - 0x28xx (no category ?) - 0x64xx .. 0x66xx (attractions) This option allows to exclude POI types from the index. The exclueded types are not indexed, but may still be searchable on a device as some devices seem to ignore most of the index, e.g. an Oregon 600 with firmware 5.00 only seems to use it for city search. If you device finds a POI name like 'Planet' when you search for 'Net' it doesn't use the index because the index created by mkgmap cannot help for that search. So, this option may help when you care about the size of the index or the memory that is needed to calculate it. The option expects a comma separated list of types or type ranges. A range is given with from-type-to-type, e.g. 0x6400-0x6405. First and last type are both excluded.A range can span multiple types, e.g. 0x6400-0x661f. Examples for usage: - Assume your style adds a POI with type 0x2800 for each addr:housenumber. It is not useful to index those numbers, so you can use --poi-excl-index=0x2800 to exclude this. - For the mentioned Oregon you may use --poi-excl-index=0x2a00-0x661f to reduce the index size.
