Yoni Amir updated SOLR-3919:
----------------------------
Description:
I am using a configuration roughly as follows:
<bool name="hl.usePhraseHighlighter">true</bool>
<bool name="hl.highlightMultiTerm">true</bool>
<int name="hl.snippets">4</int>
<bool name="hl.mergeContiguous">true</bool>
I found a strange case as follows:
I have only 1 hit in the field, so I expect that no merging will take place.
However, solr returns a highlight snippet of length 400. In effect, it
calculates the hl.snippet size times 100. With hl.snippet=10, the length is
1000. I think it is because hl.fragsize is 100 by default.
This occurs only if the hit is sufficiently close to the beginning of the
field's text - that is, if it is between the 300th and 400th character. In that
change, the first four 100-block size snippets are merged as if all of them
have a hit.
This behavior is wrong, and if there is only one hit, I don't expect solr to
merge anything for me.
