UDM_ADD_SEARCH_LIMIT(3) 1 UDM_ADD_SEARCH_LIMIT(3) 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, "<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. PHP Documentation Group UDM_ADD_SEARCH_LIMIT(3)

UDM_LOAD_ISPELL_DATA(3) 1 UDM_LOAD_ISPELL_DATA(3) udm_load_ispell_data - Load ispell data SYNOPSIS
bool udm_load_ispell_data (resource $agent, int $var, string $val1, string $val2, int $flag) DESCRIPTION
udm_load_ispell_data(3) loads ispell data. After using this function to free memory allocated for ispell data, please use udm_free_ispell_data(3), even if you use UDM_ISPELL_TYPE_SERVER mode. PARAMETERS
o $agent - A link to Agent, received after call to udm_alloc_agent(3). o $var - Indicates the source for ispell data. May have the following values: o UDM_ISPELL_TYPE_DB - indicates that ispell data should be loaded from SQL. In this case, parameters $val1 and $val2 are ignored and should be left blank. $flag should be equal to 1. Note $flag indicates that after loading ispell data from defined source it should be sorted (it is necessary for correct functioning of ispell). In case of loading ispell data from files there may be several calls to udm_load_ispell_data(3), and there is no sense to sort data after every call, but only after the last one. Since in db mode all the data is loaded by one call, this parameter should have the value 1. In this mode in case of error, e.g. if ispell tables are absent, the function will return FALSE and code and error message will be accessible through udm_error(3) and udm_errno(3). o UDM_ISPELL_TYPE_AFFIX - indicates that ispell data should be loaded from file and initiates loading affixes file. In this case $val1 defines double letter language code for which affixes are loaded, and $val2 - file path. Please note, that if a relative path entered, the module looks for the file not in UDM_CONF_DIR, but in relation to current path, i.e. to the path where the script is executed. In case of error in this mode, e.g. if file is absent, the function will return FALSE, and an error message will be displayed. Error message text cannot be accessed through udm_error(3) and udm_errno(3), since those functions can only return messages associated with SQL. Please, see $flag parameter description in UDM_ISPELL_TYPE_DB. Example #1 udm_load_ispell_data(3) example <?php if ((! udm_load_ispell_data($udm, UDM_ISPELL_TYPE_AFFIX, 'en', '/opt/ispell/en.aff', 0)) || (! udm_load_ispell_data($udm, UDM_ISPELL_TYPE_AFFIX, 'ru', '/opt/ispell/ru.aff', 0)) || (! udm_load_ispell_data($udm, UDM_ISPELL_TYPE_SPELL, 'en', '/opt/ispell/en.dict', 0)) || (! udm_load_ispell_data($udm, UDM_ISPELL_TYPE_SPELL, 'ru', '/opt/ispell/ru.dict', 1))) { exit; } ?> Note $flag is equal to 1 only in the last call. o UDM_ISPELL_TYPE_SPELL - indicates that ispell data should be loaded from file and initiates loading of ispell dictionary file. In this case $val1 defines double letter language code for which affixes are loaded, and $val2 - file path. Please note, that if a relative path entered, the module looks for the file not in UDM_CONF_DIR, but in relation to current path, i.e. to the path where the script is executed. In case of error in this mode, e.g. if file is absent, the function will return FALSE, and an error message will be displayed. Error message text cannot be accessed through udm_error(3) and udm_errno(3), since those functions can only return messages associated with SQL. Please, see $flag parameter description in UDM_ISPELL_TYPE_DB. <?php if ((! udm_load_ispell_data($udm, UDM_ISPELL_TYPE_AFFIX, 'en', '/opt/ispell/en.aff', 0)) || (! udm_load_ispell_data($udm, UDM_ISPELL_TYPE_AFFIX, 'ru', '/opt/ispell/ru.aff', 0)) || (! udm_load_ispell_data($udm, UDM_ISPELL_TYPE_SPELL, 'en', '/opt/ispell/en.dict', 0)) || (! udm_load_ispell_data($udm, UDM_ISPELL_TYPE_SPELL, 'ru', '/opt/ispell/ru.dict', 1))) { exit; } ?> Note $flag is equal to 1 only in the last call. o UDM_ISPELL_TYPE_SERVER - enables spell server support. $val1 parameter indicates address of the host running spell server. $val2 ` is not used yet, but in future releases it is going to indicate number of port used by spell server. $flag parame- ter in this case is not needed since ispell data is stored on spellserver already sorted. Spelld server reads spell-data from a separate configuration file ( /usr/local/mnogosearch/etc/spelld.conf by default), sorts it and stores in memory. With clients server communicates in two ways: to indexer all the data is transferred (so that indexer starts faster), from search.cgi server receives word to normalize and then passes over to client (search.cgi) list of normalized word forms. This allows fastest, compared to db and text modes processing of search queries (by omitting loading and sorting all the spell data). udm_load_ispell_data(3) function in UDM_ISPELL_TYPE_SERVER mode does not actually load ispell data, but only defines server address. In fact, server is automatically used by udm_find(3) function when performing search. In case of errors, e.g. if spellserver is not running or invalid host indicated, there are no messages returned and ispell conversion does not work. Note This function is available in mnoGoSearch 3.1.12 or later. Example: <?php if (!udm_load_ispell_data($udm, UDM_ISPELL_TYPE_SERVER, '', '', 1)) { echo "Error loading ispell data from server<br /> "; exit; } ?> The fastest mode is UDM_ISPELL_TYPE_SERVER. UDM_ISPELL_TYPE_TEXT is slower and UDM_ISPELL_TYPE_DB is the slowest. The above pat- tern is TRUE for mnoGoSearch 3.1.10 - 3.1.11. It is planned to speed up DB mode in future versions and it is going to be faster than TEXT mode. o $val1 - o $val2 - o $flag - RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
