Description

If you using MoinMoin with the Xapian SearchEngine in full text mode with some regex parameters, the Xapian gets disabled and the standard moinsearch will be using.

A manual restart of the MoinMoin process or Server helps. For me it seems that also that the indexing will stop and you need to rebuild it manually (atleast if you want an actual index).

Steps to reproduce

I'm bad; but I did it on our MasterMoin:

• Xapian Title Search (SearchBox)
  Titel Search

• Xapian Fulltext Search (SearchBox)
  Regex Search

• MoinSearch (SearchBox) 'coz Xapian Search is deactivated
  Title Search

with the timing/log displayed on your site you will see that _moinSearch is used and not the _xapianProcess

if you make some basic title-search regex like regex:test* everything works.... but if you switch to fulltextsearch the moin stops the xapian search.

Example

• http://master.moinmo.in (MoinMaster)

• http://rock.heavy.ch (my personal Wiki)

moinsearch.png

    * _moinSearch = 0.138s
    * base__init__ = 0.002s
    * getACL = 0.003s
    * getPageCount = 0.002s
    * getPageList = 0.137s
    * i18n_init = 0.000s
    * load_multi_cfg = 0.000s
    * run = 0.209s
    * total = 0.210s

• how MoinMoin access the Xapian Search (fulltextsearch; title search seems to be more stable)

Details

Workaround

• not using xapian-search; only moinsearch
  for me not a solution coz' xapian seems to me a lot faster and better

• hope that nobody use some wrong regex
• restart moin process and rebuild index every day

Discussion

At the moment I do not found any logs where explained to me, why the moinmoin stops using xapian search-engine...
