It looks like field was null?
Back in 4.1.0 we just assert field != null, but in newer releases it's
a real check.

Hi, thankyou Il try and get the query logged for when it next happens
Okay here are two lucene queries that cause the issue
artist:pandora /reyli barba recording:Solo el y yo/Alguien llena mi lugar
artist:Jeremih recording:Rated R (The Masterpiece) (Bear//Face Bootleg Edit)
So I think the problem is that the users are not aware of the regular
expression syntax, escaping or removing the slashes and it works
(Interestingly just removing one of the slashes
artist:pandora /reyli barba recording:Solo el y yo Alguien llena mi lugar
gives me the ParseException instead of the NullPointerException
)
Which query parser are you using? Seems like a bug if that query
parser can do this ...
ClassicQueryParser, but the point is that we provide a webservice that
allow users to use the full query syntax as it would be impossible to
second guess what the user may want to do so I dont there is a bug in
the queryparser in that that way. We just receive a text string that we
send to Lucene, I would hope if the syntax was incorrect Lucene would
just give a ParseException
But how can I fix this at my end so that Lucene returns an ParseException
rather than NullPointerException ?
We need to fix the query parser.
Do you know the earliest verion of Lucene after 4.1.0 to handle this ?
Sorry I don't offhand ... though the fix is to throw
IllegalArgumentException instead of NPE.
Why not ParseException ?
Why not just upgrade to the latest bugfix (4.10.4)?
In the past Ive generally tried to use the latest version of Lucene, but
there are usually at least some changes required even updating minor
versions. So expect 4.10.4 will give me more issues, and if its going
to throw IllegalArgumentException rather than ParseExeption not sure
that helpful.
