Enabling and disabling full text search

You can enable or disable full text search only for on-premises deployments.

Full text search (FTS) is installed by default with the AR System server . This section discusses the capabilities, performance, and administration of the FTS  feature. Topics include:

• Setting up FTS to search across multiple forms
• Re-indexing considerations
• Defining a field for FTS
• How FTS indexing works
• How FTS high availability works in a server group environment
• FTS Operation types

FTS  is typically much faster than using the native database searching functionality when searching in long text fields. It is also the only method available in AR System  for searching text within attached documents. 

With FTS , you can use your knowledge base. You can access your company's history of solving problems, which is sometimes stored in long text fields or attachments. With the FTS  option, you can easily search long text fields to find solutions to related problems.

FTS  solves many problems that users encounter when performing database searches, including:

• Searching long text and attachment fields. The FTS  option enables you to index character, diary, and attachment fields for searching, and then matches entries from those fields against the search criteria that you specify. Like database indexes, an FTS  index can greatly decrease the time required for a database search.
• Improving search performance by searching large volumes of data.
• Defining how the server interprets wildcards to customize search performance to your specific needs.
• Ranking search results according to their relevance to the search criteria. The more relevant a search result is, the greater the weight. For more information, see Causing accrued and weighted results with FTS.

To enable  FTS

1. Install  FTS  with  AR System .
   
   See  Installing  in  BMC Helix Innovation Suite  Deployment online documentation.
2. Configure the server for FTS . (See Configuring full text search.)
3. Index fields for FTS . (See Defining a field for FTS.)
4. (Optional) Add a form search field to a form. (See Providing a shortcut for specifying expanded FTS qualifications.)
5. (Optional) Set up forms for multiple-form FTS . (See Setting up FTS to search across multiple forms.)
6. Re-index, as needed. (See Re-indexing considerations.)
