[EasyHack] #44681 port to CLucene from java/Lucene

[Rene Engelhard]

Hi,

first of all: thanks for this effort, which should have been done when this
lucene dependency was introduced in the first place in OOo times.

But...

This is bad. Will that get somewhen released? And is the clucene-contribs-lib
included? (And if separate, how hard is to enable it? Patching it into "proper"
clucene is a no-go.)

As Radek says, we should (if it was only me: must) support building
against "standard" libclucene. And relying on a git snapshot is bad...

Exactly.

But he didn't post *any* makefile, so trying to write a configure check
is moot right now anyways ;-)
