Subject highlighter/fragmenter question
Date Thu, 30 Apr 2015 18:48:52 GMT
I'm not sure if this is the correct approach, so please let me know if there is a better way
to accomplish the following task

I am attempting to search an entire database for a keyword.  To do this, I indexed all the
data fields into a single "content" field with a delimiter between each field.  To search
for a matching keyword, I need only to search the "content" field.  This works well...

I also want to highlight the field and display contextual data.  The problem is, the fragmenter
slits the string into tokens based "fragmentSize" of the "content" field, which may split
the string in the middle of a data field.  I would like the string to be tokenized by the
fragmenter based on my delimiter.

I've looked at SimpleSpanFragmenter, but am not sure if that is the right class to use or
how to configure it if it is, or if I should be modifying TokenStream or some other class
to accomplish this.

Any help, ideas or links to tutorials/sample code would be greatly appreciated

Thanks in advance
