Kannan Chellappa commented on SOLR-4660:
----------------------------------------
Brief Troubleshooting (in 4.1) indicates the following
The slop specified ps matches a fragment of the document that contains all the
three words in the query and the number of characters is about 212 and the
requested frag size is 200. When the newMargin and the modifiedStartOffset
gets computed in BaseFagListBuilder (in createFieldFragList) it shortens the
fragment instead of expanding it (seem like it assumes that all matching
phrases would fit within the fragsize.
> FastVectorHighlighter: String Out of bounds exception when phrase query is
> used (pf is used in edismax)
