How do you set the position increment gap between each addition to the
same field name. Should you set it as high as possible to prevent
proximity queries from crossing it? I have been looking for the code to
find out how to put a gap between each same name field addition, but I
have been unable to find what I am looking for. Also, when using a
nearspan, things blow up if you look for something within
Integer.maximum--sic :) -- Will this be the same case for setting the
positional gap and if so is there a good max to use to keep a query from
ever crossing it?
Thanks,
Mark

In "Lucene In Action" book it says it is better practice to combine
two fields into one field and index it than use the
MultiFieldQueryParser. Do I initially index both the fields and then
index them again together? When I index them together do I index the
fieldnames or values? Can someone give me an example of how to do it?
What I do is simply index all the fields individually that need to be
searchable or just stored, but also index a general-purpose "contents"
field with all of that same text.
You can add multiple fields of the same name to a document, making it
easy to just keep appending to a "contents" field for a document. You
can see how this is done in the Lucene in Action code in the
TestDataDocumentHandler.java - however I took a cruder approach and
appended the fields together with a space in between them rather than
using the multiple valued field approach. Either technique will work
just fine.
