Hi Michael,
But in general escaping characters in a query gets tricky - if you
can
directly build queries versus pre-processing text sent to the query
parser, you'll save yourself some pain and suffering.
What do you mean by these two alternatives? That is, what exactly
could
I do better?
By "can build...", I meant if you can come up with a GUI whereby the
user doesn't have to use special characters (other than say quoting)
then you can take a collection of clauses and programmatically build
your query, without using the query parser.
The code I wound up having to write for what seemed like simple
escaping quickly got complex and convoluted - e.g. if you want to
allow "AND" as a term, and don't want it to get processed specially by
the query parser.
Also, since I did the above code the DisMaxRequestHandler has been
added to Solr, and it (IIRC) tries to be smart about handling this
type of escaping for you.
Dismax is not (yet) an option because we need the full lucene syntax
within the query.
OK - in that case sounds like you're stuck with escaping.
