implement the regex pattern analyzer with that?

This is because no constructors were generated for PatternAnalyzer. That in
turn is because the java.util.regex package is missing from the JCC command
line in PyLucene's Makefile, causing methods and constructors using classes
in that package to be skipped.
To fix this, add
--package java.util.regex \
around line 214 to PyLucene's Makefile.
It is also strongly recommended that you rebuild pyjama with --import lucene
on the JCC command line so that you don't have JCC generate wrappers
again for classes that are shared between pyjama and lucene.
Andi..
