Hi,
In the Eclipse client, when you choose to create a new work item, you can select between start from scratch, simple query, and full text query.  All of these types are just template queries--they can each be customized and can use full-text search.  Start from scratch gives you no conditions by default.  Simple query gives you status, filed against, owner, and full-text by default.  Full text query gives you full-text by default.  https://jazz.net/library/article/824 describes more about how full-text query works.
