# Stemming With Term Actions

There are four term actions that accept the `Stemming` parameter: `TermGetAll`, `TermGetBest`, `TermExpand`, and `TermGetInfo`. The general idea is always the same: whether to return the results in stemmed form (`Stemming=True`), or unstemmed form (`Stemming=False`). However, the behavior of this parameter depends on the action that you use.

- `TermGetAll` and `TermGetInfo`. The `Stemming` parameter works normally for the `TermGetAll` and `TermGetInfo` actions. It specifies whether to return the results in stemmed or unstemmed form.

- `TermGetBest`. Only the terms which have more document occurrences than the `UnstemmedMinDocOccs` configuration parameter are returned.

- `TermExpand`. When the `Type` parameter is `DocOccs` and the `Stemming` parameter is `False` for the `TermExpand` action, it returns counts only for the exact unstemmed form. Counts for the stemmed form are disregarded.
