IndexedSearchUtility
Class with common methods used across various classes in the indexed search.
Implementation is provided by various people from the TYPO3 community.
Table of Contents
Methods
- getExplodedSearchString() : array<string|int, mixed>
- Takes a search-string (WITHOUT SLASHES or else it'll be a little spooky , NOW REMEMBER to unslash!!) Sets up search words with operators.
- isTableUsed() : bool
- Check if the tables provided are configured for usage. This becomes necessary for extensions that provide additional database functionality like indexed_search_mysql.
- md5inthash() : int
- md5 integer hash Using 7 instead of 8 just because that makes the integers lower than 32 bit (28 bit) and so they do not interfere with UNSIGNED integers or PHP-versions which has varying output from the hexdec function.
- milliseconds() : int
- Gets the unixtime as milliseconds.
- getOperator() : string|null
- This returns an SQL search-operator (eg. AND, OR, NOT) translated from the current localized set of operators (eg. in danish OG, ELLER, IKKE).
- split() : mixed
- Used to split a search-word line up into elements to search for. This function will detect boolean words like AND and OR, + and -, and even find sentences encapsulated in "" This function could be re-written to be more clean and effective - yet it's not that important.
Methods
getExplodedSearchString()
Takes a search-string (WITHOUT SLASHES or else it'll be a little spooky , NOW REMEMBER to unslash!!) Sets up search words with operators.
public
static getExplodedSearchString(string $sword, string $defaultOperator, array<string|int, mixed> $operatorTranslateTable) : array<string|int, mixed>
Parameters
- $sword : string
-
The input search-word string.
- $defaultOperator : string
- $operatorTranslateTable : array<string|int, mixed>
Return values
array<string|int, mixed>isTableUsed()
Check if the tables provided are configured for usage. This becomes necessary for extensions that provide additional database functionality like indexed_search_mysql.
public
static isTableUsed(string $tableName) : bool
Parameters
- $tableName : string
-
Table name to check
Return values
bool —True if the given table is used
md5inthash()
md5 integer hash Using 7 instead of 8 just because that makes the integers lower than 32 bit (28 bit) and so they do not interfere with UNSIGNED integers or PHP-versions which has varying output from the hexdec function.
public
static md5inthash(string $stringToHash) : int
Parameters
- $stringToHash : string
-
String to hash
Return values
int —Integer interpretation of the md5 hash of input string.
milliseconds()
Gets the unixtime as milliseconds.
public
static milliseconds() : int
Return values
int —The unixtime as milliseconds
getOperator()
This returns an SQL search-operator (eg. AND, OR, NOT) translated from the current localized set of operators (eg. in danish OG, ELLER, IKKE).
protected
static getOperator(string $operator, array<string|int, mixed> $operatorTranslateTable) : string|null
Parameters
- $operator : string
-
The possible operator to find in the internal operator array.
- $operatorTranslateTable : array<string|int, mixed>
-
an array of possible operators
Return values
string|null —If found, the SQL operator for the localized input operator.
split()
Used to split a search-word line up into elements to search for. This function will detect boolean words like AND and OR, + and -, and even find sentences encapsulated in "" This function could be re-written to be more clean and effective - yet it's not that important.
protected
static split(string $origSword[, string $specchars = '+-' ][, string $delchars = '+.,-' ]) : mixed
Parameters
- $origSword : string
-
The raw sword string from outside
- $specchars : string = '+-'
-
Special chars which are used as operators (+- is default)
- $delchars : string = '+.,-'
-
Special chars which are deleted if the append the searchword (+-., is default)
Return values
mixed —Returns an ARRAY if there were search words, otherwise the return value may be unset.
