udm_add_search_limit -- Add various search limits
Description
int udm_add_search_limit (int agent, int var, string val)
udm_add_search_limit() returns TRUE on success,
FALSE on error. Adds search restrictions.
agent - a link to Agent, received after call to udm_alloc_agent().
var - defines parameter, indicating limit.
val - defines value of the current parameter.
Possible var values:
-
UDM_LIMIT_URL - defines document URL limitations to limit search through subsection of
database. It supports SQL % and _ LIKE wildcards, where % matches any number of characters, even
zero characters, and _ matches exactly one character. E.g. http://my.domain.__/catalog may stand
for http://my.domain.ru/catalog and http://my.domain.ua/catalog.
-
UDM_LIMIT_TAG - defines site TAG limitations. In indexer-conf you can assign specific TAGs
to various sites and parts of a site. Tags in mnoGoSearch 3.1.x are lines, that may contain
metasymbols % and _. Metasymbols allow searching among groups of tags. E.g. there are links with
tags ABCD and ABCE, and search restriction is by ABC_ - the search will be made among both of the
tags.
-
UDM_LIMIT_LANG - defines document language limitations.
-
UDM_LIMIT_CAT - defines document category limitations. Categories are similar to tag
feature, but nested. So you can have one category inside another and so on. You have to use two
characters for each level. Use a hex number going from 0-F or a 36 base number going from 0-Z.
Therefore a top-level category like 'Auto' would be 01. If it has a subcategory like 'Ford', then
it would be 01 (the parent category) and then 'Ford' which we will give 01. Put those together and
you get 0101. If 'Auto' had another subcategory named 'VW', then it's id would be 01 because it
belongs to the 'Ford' category and then 02 because it's the next category. So it's id would be
0102. If VW had a sub category called 'Engine' then it's id would start at 01 again and it would
get the 'VW' id 02 and 'Auto' id of 01, making it 010201. If you want to search for sites under
that category then you pass it cat=010201 in the url.
-
UDM_LIMIT_DATE - defines limitation by date document was modified.
Format of parameter value: a string with first character < or >, then with no space
- date in unixtime format, for example:
Udm_Add_Search_Limit($udm,UDM_LIMIT_DATE,"<908012006");
If > character is used, then search will be restricted to those documents having
modification date greater than entered. If <, then smaller.
