# FieldText Search

FieldText queries are `Query`, `Suggest`, or `SuggestOnText` actions that include the `FieldText` parameter. You can combine this parameter with the `Text` parameter to restrict the results that your query returns to documents that contain a specific value in a specified field. You can also use the `FieldText` parameter on its own to query for documents that contain specific values in specific fields. Micro Focus does not recommend this type of query because it slows the IDOL Content component processing speed.

To specify how documents must match fields and field values to return as results, the `FieldText` parameter uses field specifiers which identify the pattern of values in fields. These field specifiers fall into three groups, described in these sections:

- Field Specifiers for Common Restrictions

- Field Specifiers for Advanced Restrictions

- Field Specifiers to Bias Result Scores

NOTE: FieldText queries that include commas and braces within the query have specific percent-encoding requirements. For information about percent-encoding, see FieldText.
