udm_add_search_limit - Add various search limits

SYNOPSIS

       bool udm_add_search_limit (resource  $agent, int  $var, string  $val)

DESCRIPTION

       udm_add_search_limit(3) adds search restrictions.

PARAMETERS

	      o $agent
		- A link to Agent, received after call to udm_alloc_agent(3).

	      o $var
		- Defines the parameter, indicating limits. Possible $var values:

		     o UDM_LIMIT_URL  - defines document URL limitations to limit the search through subsection of the database. It supports SQL %
		       and _ LIKE wildcards, where % matches any number of characters, even zero characters, and _ matches exactly one	character.
		       E.g. http://www.example.___/catalog may stand for http://www.example.com/catalog and http://www.example.net/catalog.

		     o 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.

		     o UDM_LIMIT_LANG - defines document language limitations.

		     o 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.

		     o UDM_LIMIT_DATE  -  defines  limitation  by  date the document was modified.  Format of parameter value: a string with first
		       character < or >, then with no space - date in unixtime format, for example:

		     Example #1

			    <?php
			    udm_add_search_limit($udm, UDM_LIMIT_DATE, "&lt;908012006");
			    ?>
		      If > character is used, then the search will be restricted to those  documents  having  a  modification  date  greater  than
		     entered, if <, then smaller.

	      o $val
		- Defines the value of the current parameter.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.
