# Text

Note: This parameter description applies only to the TermExpand action.

The term to expand according to the specified Expansion.

The following table describes the value to set in the `Text` parameter for each type of Expansion.

Expansion | Text | TermExpand returns
--- | --- | ---
`Fuzzy` | A misspelled term. | Terms with similar spelling to your term.
`Synonym` | A synonym link from a synonym query. (See Synonym) | The terms and phrases that the synonym link corresponds to.
`Stem` | Any term. | A list of terms that have the same word stem as the specified term.
`Wild` | A Wildcard term. | A list of terms that the Wildcard term expands to.

When you set Expansion to `Fuzzy` or `Wild`, you can add a field restriction. If you set a field restriction, TermExpand returns only terms that appear in this field. You can use only fields that you set in the UnstemmedTrackFields configuration parameter.

Specify field restrictions in the form `Text=Text:Field`, where:

- `Text` is the misspelled or Wildcard term to expand.

- `Field` is the field to restrict by.
