Searching from the UI

      Full Text Search can be performed from the Couchbase Web Console.

      Access the Full Text Search User Interface

      The user interface for Full Text Search is provided by the Couchbase Web Console. In order to proceed, you must have permission to log into the console, create indexes, and perform searches. For information on Role-Based Access Control, see Authorization.

      The example provided in this section assumes that you have also loaded the travel-sample bucket: you will perform your Full Text Search operations on the data in this bucket. For instructions on how to load this sample bucket, see Sample Buckets.

      Once you have the appropriate credentials, and have loaded the travel-sample bucket, access the Couchbase Web Console by typing http://<server_name>:8091 into the address-field at the top of your browser, and then hitting return. The login screen appears as follows:

      fts login screen

      Enter your username and password, and left-click on the Sign In button. The Couchbase Web Console now appears, with the Dashboard for the cluster displayed:

      fts console initial

      Note that the appearance of the main panel of the Dashboard varies, in accordance with customizations that have been performed. For information, see Manage Statistics.

      To access the Full Text Search screen, left-click on the Search tab, in the navigation bar at the left-hand side:

      fts select search tab

      The Full Text Search screen now appears, as follows:

      fts fts console initial

      The console contains areas for the display of indexes and aliases: but both are empty, since none has yet been created.

      Perform a Query

      To perform a query, simply type a term into the interactive text-field that appears to the left of the Search button on the row for the index you have created. For example, restaurant. Then, left-click on the Search button:

      fts ui search for term

      A Search Results page now appears, featuring documents that contain the specified term:

      fts ui search results page

      By left-clicking on any of the displayed document IDs, you bring up a display that features the entire contents of the document.

      Advanced Settings and Other Features

      On the Search Results page, to the immediate right of the Search button, at the top of the screen, appears the show advanced query settings checkbox. Check this to display the advanced settings:

      fts advanced query settings

      Three interactive text-fields now appear underneath the Search panel: Timeout (msecs), Consistency Level, and Consistency Vector. Additionally, the JSON for Query Request panel displays the submitted query in JSON format. Note the show command-line curl example checbox, which when checked, adds to the initial JSON display, to form a completed curl command:

      fts ui curl example

      This example can be copied by means of the Copy to Clipboard button, pasted (for example) into a standard console-window, and executed against the prompt. This feature therefore provides a useful means of extending experiments initially performed with the UI into a subsequent console-based, script-based, or program-based context. (Note, however, that the addition of credentials for authentication are required for execution of the statement outside the context of the current session within Couchbase Web Console. See Searching with the REST API for an example.)

      Note also the Show Scoring checkbox that appears prior to the entries in the Results for travel-sample-index panel. When this is checked, scores for each document in the list are provided. For example:

      fts ui query scores display

      Finally, note the query syntax help link that now appears under the Search interactive text-field:

      fts query syntax help link

      This link takes the user to the documentation on Supported Queries. Such a query can be specified in the Search interactive text-field, thereby allowing a search of considerable complexity to be accomplished within Couchbase Web Console.

      Query String Query is the only type of query that can be executed by means of this field.
