Installation
As any other extension. Put the extension in the “extensions” folder and run the setup again.
If the database is big, the index creation can run for a long time. It is possible to populate the full-text index by calling the following page:
<itop_url>/env-production/combodo-fulltext-search/populate-search-index.cli.php
Configuration
| Parameter | Type | Description | Default value |
|---|---|---|---|
| object_weight_factor | array | Weight factor to apply for a given object name (format: 'classname' ⇒ 'value') the values can vary from 0 to 10 generally (0 means no results for this class). The default is 1 for every class not specified. The modification of this parameter needs a complete re-indexation of the database. | array( 'Organization' => 2.0, 'Person' => 1.5, 'Location' => 1.2, 'SLT' => 0.8, ) |
| sentence_weight_factor | float | Weight factor for searches with multiple words matching exactly the list of words in that order. | 10.0 |
| mandatory_weight_factor | float | Weight factor for searches with all the words of the search matching at least once. | 2.0 |
| start_with_weight_factor | float | Weight factor for searches with one word matching the beginning. | 0.5 |
| max_interactive_index_update_time_in_sec | integer | Time in seconds allowed for direct indexation update on change. | 5 |
| background_index_refresh_period_in_min | integer | Period in minutes for background indexation. | 5 |
| background_max_indexation_time_in_min | integer | Execution time limit in minutes for background indexation. | 5 |
| background_index_full_rebuild_enabled | boolean | Allow daily rebuild of the index. | true |
| background_index_full_rebuild_time | hour | Starting hour of the full rebuild of the index. | '01:30' |
Get feedbacks from your users about searches they made which do not return in the top 5, something which every users would expect to get first.
Then fine tune the above parameters using the debug mode on those sampling searches.
Then fine tune the above parameters using the debug mode on those sampling searches.
Background behavior
Searching for one word When searching for a single word (example: demo) the following researches 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 researches 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
As
- is a keyword to exclude a word, it is replaced by _ which is another keyword to represent any single character
Computing weight
Each search is bringing points calculated by MySQL fulltext search, which are then weighted with the configuration parameters set.
Administrators only have access to:
- Global search management menu which allow to rebuild the indexes after a change of configuration parameter:
object_weight_factor. - debug menu which display details on how the result ordering is generated, based on weight.

Usage
Just type the words in the global search field, then enter or click on the magnifier icon to get the result :
Tips to fine tune your search
Add
+ at the beginning of required word UserRequest:+PHP error
will search for User Requests which contain mandatorily 'PHP' and maybe 'error'
Add
- at the beginning of forbidden word UserRequest:PHP -closed
will search for User Requests which contain 'PHP' but not 'closed' (this exclude all UserRequest with status=closed)
Add
* at the end of an incomplete word Organization:Combo*
will search for Organization which contain a word starting with 'Combo'
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.
| Restrict previous search to a single class | Expend back to all classes |
|---|---|
 |  |
 |
Add
<class-name>: at the beginning of a search pattern to limit the search to objects of this classe or one of its descendants FunctionalCI:combodo
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).
Displaying matching words
A menu allow to display some of the fields which have matched the requested pattern
Displaying related objects
On each returned object, you can request related objects:
