Properties
integer $_endOffsetEnd in source text
Details
- Type
- integer
integer $_positionIncrementThe position of this token relative to the previous Token.
The default value is one.
Some common uses for this are:
Set it to zero to put multiple terms in the same position. This is
useful if, e.g., a word has multiple stems. Searches for phrases
including either stem will match. In this case, all but the first stem's
increment should be set to zero: the increment of the first instance
should be one. Repeating a token with an increment of zero can also be
used to boost the scores of matches on that token.
Set it to values greater than one to inhibit exact phrase matches.
If, for example, one does not want phrases to match across removed stop
words, then one could build a stop word filter that removes stop words and
also sets the increment to the number of stop words removed before each
non-stop word. Then exact phrase queries will only match when the terms
occur with no intervening stop words.

Methods
__construct(string $text, integer $start, integer $end) : voidObject constructor
Parameters
| Name | Type | Description |
|---|---|---|
| $text | string | |
| $start | integer | |
| $end | integer |
getEndOffset() : integerReturns this Token's ending offset, one greater than the position of the last character corresponding to this token in the source text.
Returns
| Type | Description |
|---|---|
| integer |
getPositionIncrement() : integerReturns the position increment of this Token.
Returns
| Type | Description |
|---|---|
| integer |
getStartOffset() : integerReturns this Token's starting offset, the position of the first character corresponding to this token in the source text.
Note:
The difference between getEndOffset() and getStartOffset() may not be equal
to strlen(Zend_Search_Lucene_Analysis_Token::getTermText()), as the term text may have been altered
by a stemmer or some other filter.
Returns| Type | Description |
|---|---|
| integer |
getTermText() : stringReturns the Token's term text.
Returns
