Queryparser croaking on "[" and "]"
Hi,
I'm currently building a small app that allows searching of Java sourcecode.
The problem I'm getting is when parsing a query string that contains an
array specifier (ie. String[] or int[][]) the query parser seem to croak
with a
Lexical error at line XX, column XX. Encountered: after : "[]"
So what am I doing wrong / what should I write to fix this?

SerializableRAMDirectory
Posted by Karl Oie <ka...@gan.no>.
Hi, I just added the Serializable implementation keyword to the RAMDirectory
implementation. This way I can just write the whole RAMDirectory to a
database blob for storage. After reading the RAMDir from the blob again I
can successfully perform searches on the new instance.
This started out because I got too many "too many open files" exceptions
using the FSDirectory. Then I tried to create a BLOBDirectory
implementation, but found that the lucene In/OutputStream classes to require
seek(). So when lucene wants to open a file in a BLOBDirectory I had to
fetch the whole BLOB for the file into memory so I could provide all the
functions required by the lucene Directory interface.
Since the RAMDirectory already works great in-memory, serializing it to the
BLOB after read/write sounded like a just as good idea.
If there is nothing I have overseen here I would suggest to add the
Serializable implementation keyword to the RAMDirectory implementation
because that was all it required.

This is because the query parser uses [] to denote ranges of numbers.
(I always thought this was a bad choice of syntax for exactly this
reason.)
