| searching.</p> |
| <p><p>The default value is one.</p> |
| <p><p>Some common uses for this are:</p> |
| <ul><li>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.</li><li>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.</li></ul> |
