Re: jena-text highlighting support
Hello,
With the extraneous part of the original email having been split-off, I'm interested to know if and how other users have provided for highlighting of Lucene search matches when using jena-text.
If the literals are relatively short then perhaps highlighting where a match was found by Lucene is not considered necessary; however, if the literals are several hundreds of code-points then it becomes more useful to help with ultimately displaying results to users. It seems like it might be feasible to provide a 4th return parameter that could identify the start and end of each match in the returned literal.
Thanks,
Chris

While I'm relying on jena-text in my application (Skosmos), there hasn't
been any need for highlighting since the matched strings are typically
very short (labels of SKOS concepts) and in most cases prefix matching
is used so the start of the match is also the start of the label.

That's good especially if when not using it has no impact on performance.
