I'm trying to highlight a field and I'm getting an exception thrown, only on
certain search terms though. I am fairly certain that the cause of the
problem is through having synonyms on the highlighted field as I have had
highlighting working in the past on other fields.
The added complication is that the field that I am highlighting also has
ngramming and stemming. I think what is happening is that the highlighting
cannot match the criteria (which happens to be a synonym) against the actual
string retrieved from the index and crashes, I think if the string found is
greater than a certain number of characters.
I wonder if anyone has experienced this problem and knows how to get around
it?
Basically, highlighting on synonym fields is no problem, but
highlighter doesn't support n-gram fields. FastVectorHighlighter
supports fixed-length (minGramSize==maxGramSize) n-gram fields.
