# FieldCheck

The `FieldCheck` option combines results based on the hash value of their FieldCheckType field. The FieldCheckType field holds a value that is frequently used to restrict results (for example, a field that stores category names). When Content indexes a FieldCheckType field, it stores it in a fast lookup table in memory, so that it can return quickly.

For example:

    http://ContentHost:port/action=Query&Text=The best thing to do in your spare time&Combine=FieldCheck

In this example, Content is configured to store the `Category` field as a FieldCheckType field.

If Content contains 50 documents that match the query text, of which eight contain a `Category` field with the value `Sport`, five contain a `Category` field with the value `Gardening`, and one contains a `Category` field with the value `Cooking`, the above query returns only three results:

- the most relevant of the documents whose `Category` contains the value `Sport`.

- the most relevant of the documents whose `Category` contains the value `Gardening`.

- the document whose `Category` contains the value `Cooking`.

NOTE: If you set URLAnalysis to `True` in the `[Server]` section of the Content component configuration file, you cannot identify a field as a FieldCheckType field, because Content automatically uses the domain of the URL it finds in the document ReferenceType fields as the `FieldCheck` value.
