udm_load_ispell_data — Load ispell data
$agent
, int $var
, string $val1
, string $val2
, int $flag
)udm_load_ispell_data() loads ispell data.
After using this function to free memory allocated for ispell data, please
use udm_free_ispell_data() , even if you use
UDM_ISPELL_TYPE_SERVER
mode.
agent
A link to Agent, received after call to udm_alloc_agent() .
var
Indicates the source for ispell data. May have the following values:
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() , 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 returnFALSE
and code and error message will be accessible through udm_error() and udm_errno() .
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() and udm_errno() ,
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() 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.
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() and
udm_errno() , 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.
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
parameter 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() 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()
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.
Example:Note:
This function is available in mnoGoSearch 3.1.12 or later.
<?php
if (! udm_load_ispell_data ( $udm , UDM_ISPELL_TYPE_SERVER , '' , '' , 1 )) {
echo "Error loading ispell data from server<br />\n" ;
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 pattern 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.
val1
val2
flag
成功时返回 TRUE
, 或者在失败时返回 FALSE
。
Example #2 udm_load_ispell_data() example
<?php
if (! udm_load_ispell_data ( $udm , UDM_ISPELL_TYPE_DB , '' , '' , 1 )) {
printf ( "Error #%d: '%s'\n" , udm_errno ( $udm ), udm_error ( $udm ));
exit;
