If an user do a single stupid fulltext search, the memory consumption goes too high. Depend on the environment of the moinmoin this can lead to several unwanted problems.

== Steps to reproduce ==
## Describe the steps needed to reproduce the bug. If we can't reproduce it, we  probably can't fix it.
I told ThomasWaldmann what the problem is<<FootNote(I guess you need to have a wiki with a few hundred pages at least, to reproduce this)>>, in general:
 1. Do a search
 2. Memory goes up and up (a single process, from ~60MB to 700MB)
 3. After a few seconds or minutes you either got your search back or process get killed (to much memory usage) and error message is shown

 

== Example ==
##Add URL that show the bug, screenshot or test wiki markup that fail...

##URL: 

After a few seconds the memory goes form ~ 60MB up to 800MB, with a single search query!

== Component selection ==

 * action/fullseach.py
 * maybe xapian

== Details ==


## If a traceback is not available, please fill in the details here:
|| '''!MoinMoin Version''' || 1.9.3 ||
|| '''OS and Version''' || Ubuntu ||
|| '''Python Version''' || 2.5 ||
|| '''Server Setup''' || Apache / mod_wsgi (5 processes, 15 threads)||
|| '''Server Details''' || 4 GB Memory / P4 2.6GHZ ||
|| '''Language you are using the wiki in''' (set in the browser/UserPreferences) || de ||

I could also reproduce the same problems under an different server (16GB Memory, Xeon 8x2.33GHz):
 * latest moin from hg 1.9.x
 * python 2.7
 * xapian 1.2.7
 * uwsgi 0.9.9.1
 * nginx 1.0.6

== Workaround ==
## How to deal with the bug until it is fixed
 * disable fulltext search
 * or filter out some searches

= Discussion =
A workaround like [[http://moinmo.in/MarcelH%C3%A4fner/Bleeding%20Edge#Limit_Search|this]] is not enough, we need a better filter or generaly a better result list management (less memory usage in generaly).
