First, it only counts if you add multiple entries for the field. Consider the following <doc> <field name=“blah”>a b c</field> <field name=“blah”>def</field> </doc>
where the field has a positionIncrementGap of 100. The term positions of the entries are a:1 b:2 c:3 d:103 e:104 f:105 Now consider the doc where there’s only one field: <doc> <field name=“blah”>a b c d e f</field> </doc> The term positions are a:1 b:2 c:3 d:4 e:5 f:6 The use-case is if you, say, index individual sentences and want to match two or more words in the _same_ sentence. You can specify a phrase query where the slop is < the positionIncrementGap. So in the first case, if I search for “a b”~99 I’d get a match. But if I searched for “a d”~99 I wouldn’t.
