Query validation in web app
Lucene reacts pretty badly to non-wellformed queries, not throwing a
checked/unchecked Exception but throwing an Error. The error message is also
unintelligible to a user (non-developer).
How are people checking/validating queries from a web-app?
I have some checked-in code in sandbox that does javascript validation, but I
wonder if there's a smarter way to do query validation..

There was one condition we tightened up recently where a ParseException
was not being thrown, but now it is.
This was when there were too many boolean queries, and this exception
is now converted to a ParseException.

Sorry, my bad. Was it ever throwing Errors? Probably not, but somehow I had the
impression it was..

Kelvin,
In what scenarios does QueryParser fail without throwing a
ParseException?
I think we should fix those cases to ensure a ParseException is thrown.

Neither! :-) I was just wondering if there were better ways to do it, that's
all. I'm a regex newbie and I found it rather difficult to validate the entire
Lucene query syntax (including escaping!) using regex.
Anyway, I'm writing unit tests for the query validator right now courtesy of
jsunit...

So should I be embarrassed or should Kelvin be flattered :-)?

Look at the javascript validator in the Lucene sandbox. A quite elegant
solution, unless you're opposed to using javascript.
