Enhanced global search
- Enhanced global search
- Use a faster and more relevant global search with easy-to-filter results
- Client Store, iTop Hub
This extension replace the standard global search with a faster and more accurate search.
Users can improve results accuracy by specifying required, optional and denied words.
Administrator can fine-tune the results relevance, by changing configuration parameters.
It uses MySQL fulltext feature to perform the global search.

Create, update or delete object
When ever a user create, update or delete an object in iTop, the
extension will recompute the fulltext search indexes. If it cannot
do it within
second, it flags out-of-date indexes and they will be processed by
the itop-cron using a background task.
You may see that warning message when you change an organization name for example, as it is present in most iTop objects, so a lot of indexes will have to be updated, more than what can be processed in a user acceptable delay
Searching for one word When searching for a single word (example: demo) the following searches are done:
The word: demo
The words starting with the search: demo*
Searching for multiple words
When searching for multiple words, (example: user-level lock) the following searches are done:
The exact sentence entered: “user_level lock”
All the words are present: +user_level +lock
At least one word is present: user_level lock
- is a keyword to exclude a word, it is replaced
_ which is another keyword to represent any single
Each search is bringing points calculated by MySQL fulltext search, which are then weighted with the configuration parameters set.
What values to set
To ensure that the search will be efficient within your iTop, there are additional actions for Administrator users:
Global search management action which allow to rebuild the indexes after a change of configuration parameter:
Debug action which display details on how the result ordering is generated, based on weight.
user_level lock has a MySQL provided weight
“user_level lock” has the above weight *
Total Score is the sum of the various scores *
Debugaction on those “sampling searches”.
Global Search Management
There is an administrator menu, which allow to
see on-going status of re-indexation processing
run re-indexation tasks for those who do not have access to their iTop system (Use with caution!!!)
Read carefully the text near the checkbox, it is refreshed based on the check status.
First checkbox delete all indexes.
Second checkbox alone is similar to using the /script/refresh-search-index.cli.php on your iTop system
Third checkbox, will request the cron to do the work in background, rather than doing it real-time interactively. Background computation is performed every
background_index_refresh_period_in_minminutes for a maximum duration of
background_max_indexation_time_in_minminutes before stopping until the next run.
Consequences of your choices:
Checking the first one, without the second one, leads to no more index at all
Checking the first and second without the third one, leads to timeout.
Checking the 3 may work, but it's much better to use the /script/populate-search-index.cli.php on your server. It will be faster and more efficient than truncating the tasks in multiple small pieces of work.
Interactive in most cases will timeout and fail (apart from empty test databases).
A better alternative to using this administrative page within iTop, is to run in CLI the below scripts:
populate-search-index.cli.php --verbose=0/1 --set-limit=<numer of second>
It puts your iTop under maintenance
Drop the index table
Reopen access to your iTop (also global search will not respond)
Rebuild the fulltext index table
wait_timeoutis around 28 800 before running
To prevent situation where the script and the cron would both try to recompute indexes at the same time, we have used a MySQL lock.
Some distribution, overwrite the default MySQL/MariaDB value for
wait_timeout parameter and put 600 (seconds). That
delay is not enough to populate indexes for a big database, as a
result, the script will return “MySQL has gone
away” which is the answer to the unlock request done by
the script when it finishes. In reality, the work was done, indexes
have been recomputed, the error is misleading, it's just the lock
which could not be released, because after
wait_timeout seconds of inactivity on that session,
MySQL/MariaDB has decided it was useless to wait more, and released
⇒ To get rid of that error, just restore default value for
wait_timeout (28 800).
refresh-search-index.cli.php --verbose=0/1 --set-limit=<numer of second>
It does not put iTop under maintenance
It takes every existing index, and re-index them one by one
Missing index are not created. So the script is not adequate for an existing database on which you just installed the extension.
It is useful to remove entries corresponding to recently archived objects
Just type the words in the global search field,
enter or click on the magnifier icon to get the
Tips to specify your search
+at the beginning of required word
will search for User Requests which contain mandatorily 'PHP' and maybe 'error'
-at the beginning of excluded word
will search for User Requests which contain 'PHP' but not 'closed' (this exclude all UserRequest with status=closed)
*at the end of an incomplete word
will search for Organization which contain a word starting with 'Combo' and the exact word 'Grenoble'. This is useless in single word search, as it does it automatically.
Restricting the search to a class
By default the search searchs on all Classes with category searchable, including abstract classes, such as Ticket, Contact or FunctionalCI.
<class-name>:at the beginning of a search pattern to limit the search to objects of this classe or one of its descendants
will search for any FunctionalCI which contains “combodo”, so the returned objects can be Server, PC, Enclosure,…
The class name can be the internal name (like FunctionalCI) of the display name in the current language used (like CI fonctionnel).
