How does a full-text index work?

A full-text index is a special type of index that provides index access for full-text queries against character or binary column data. A full-text index breaks the column into tokens and these tokens make up the index data.

How do you implement full-text search?

Steps to Implement Full-Text Search in SQL Server

1. Create a Full-Text Catalog (to store Full-Text indexes).
2. Define Full-Text Index on Table or Indexed View.
3. Run Full-Text Search Queries using CONTAINS or FREETEXT to find words and phrases.

How do I do a full text search in SQL?

The SQL Server process uses the following components for full-text search:

1. User tables. These tables contain the data to be full-text indexed.
2. Full-text gatherer.
3. Thesaurus files.
4. Stoplist objects.
5. SQL Server query processor.
6. Full-Text Engine.
7. Index writer (indexer).
8. Filter daemon manager.

How to manually populate a full text index?

An incremental population is an alternative mechanism for manually populating a full-text index. If a table experiences a high volume of inserts, using incremental population can be more efficient that using manual population. You can run an incremental population for a full-text index that has CHANGE_TRACKING set to MANUAL or OFF.

How does the full text engine update the index?

The incremental population then updates the full-text index for rows added, deleted, or modified after the last population, or while the last population was in progress. At the end of a population, the Full-Text Engine records a new timestamp value. This value is the largest timestamp value that SQL Gatherer has found.

Why are changes not reflected in full text index?

Data changes made through WRITETEXT and UPDATETEXT are not reflected in the full-text index, and are not picked up with change tracking. For tables containing a timestamp column, you can use incremental population instead of change tracking.

Do you need to have table change tracking enabled for full text indexing?

You do NOT need to have table change tracking enabled for Full Text Indexing Change Tracking and Full Text Indexing autopopulate to work. Running the following query from the database will reveal the last time your full text indexer ran a crawl. When autopopulate is on, the crawl_end_date should change after you insert data into the table.
