`FTS Configuration dialog`:index:
|
|
*********************************
|
|
|
|
Use the *FTS Configuration* dialog to configure a full text search. A text search configuration specifies a text search parser that can divide a string into tokens, along with dictionaries that can identify searchable tokens.
|
|
|
|
The *FTS Configuration* dialog organizes the development of a FTS configuration through the following dialog tabs: "*General*, *Definition*, and *Tokens*. The *SQL* tab displays the SQL code generated by dialog selections.
|
|
|
|
Click the *General* tab to begin.
|
|
|
|

|
|
:alt: FTS configuration dialog general tab
|
|
|
|
Use the fields in the *General* tab to identify a FTS configuration:
|
|
|
|
* Use the *Name* field to add a descriptive name for the FTS configuration. The name will be displayed in the *pgAdmin* tree control.
|
|
* Use the drop-down listbox next to *Owner* to specify the role that will own the configuration.
|
|
* Select the name of the schema in which the FTS configuration will reside from the drop-down listbox in the *Schema* field.
|
|
* Store notes about the FTS configuration in the *Comment* field.
|
|
|
|
Click the *Definition* tab to continue.
|
|
|
|
.. image:: images/fts_configuration_definition.png
|
|
:alt: FTS configuration dialog definition tab
|
|
|
|
Use the fields in the *Definition* tab to define parameters:
|
|
|
|
* Select the name of the text search parser from the drop-down listbox in the *Parser* field.
|
|
* Select a language from the drop-down listbox in the *Copy Config* field.
|
|
|
|
Click the *Tokens* tab to continue.
|
|
|
|
.. image:: images/fts_configuration_tokens.png
|
|
:alt: FTS configuration dialog tokens tab
|
|
|
|
Use the fields in the *Tokens* tab to add a token:
|
|
|
|
* Use the *Tokens* field to specify the name of a token.
|
|
* Click the *Add* icon (+) to create a token.
|
|
* Use the *Dictionaries* field to specify a dictionary.
|
|
|
|
Repeat these steps to add additional tokens; to discard a token, click the trash icon to the left of the row and confirm deletion in the *Delete Row* popup.
|
|
|
|
Click the *SQL* tab to continue.
|
|
|
|
Your entries in the *FTS Configuration* dialog generate a SQL command (see an example below). Use the *SQL* tab for review; revisit or switch tabs to make any changes to the SQL command.
|
|
|
|
**Example**
|
|
|
|
The following is an example of the sql command generated by user selections in the *FTS Configuration* dialog:
|
|
|
|
.. image:: images/fts_configuration_sql.png
|
|

|
|
|
|
The example shown demonstrates creating a FTS configuration named *meme_phrases*. It uses the *default* parser.
