Thanks for these suggestions. The ideas of adding taxonomy-related terms
to the documents is an interesting one and bears some thought. However, if
I have to pre-process the corpus to determine which terms to add, and then
to add them, it would seem that I've already accomplished my primary goal
how about this:
assuming that your taxonomies are tree-like structures, you could expand
every term in the documents to be indexed with the path where they
belong in the tree (i.e. all hypernyms and hyponyms) - for this you use
the same technique as when using thesauri. This will allow you to enter

Adding a new document does not immediately modify an index, so the time
it takes to add a new document to an existing index is not proportional
to the index size. It is constant. The execution time of optimize()
is proportional to the index size, so you want to do that only if you
really need it.
Browsing through some of previous discussion, but I have to say that I
couldn't find a solution for this. Would you mind provide more clue on this?

You are using an Analyzer that throws out non-alphanumeric characters,
StandardAnalyzer most likely.
You can create your own Analyzer to do exactly what you want. A sample
Analyzer is in the Lucene FAQ at http://jguru.com/ .

I believe it takes constant time to add a new document to an index
because when adding a new document a new segment is created on the
disk, 'separate' from the other, existing, index segments.
The size of the index may come into play when this new segment has to
be merged with the existing segments
One of my clients is asking for an old-style boolean query search on my keywords
fields. A string might look like this:
"oracle admin*" and java and oracle and ("8.1.6" or "8.1.7") and ("solaris" or
"unix" or "linux")
There would probably be need for nested parenthesis, although I can't

Or use the set method in QueryParser to ask it to automatically lower case
those terms. Patch for that was added before 1.3RC1 (check javadocs

Ok, thanks Otis,
you have to write the terms lowercase when you're searching with wildcards.
