# FieldCheckType

Whether to hash the values of fields with this property for fast retrieval. Type `true` to map the values of the associated PropertyFieldCSVs field to integers (by hashing and storing them in memory), to make them available for especially fast retrieval. Typically, you assign `FieldCheckType` to fields where you frequently use the entire value to restrict results (for example, a field that stores category names).

Refer to the IDOL Server Administration Guide for more details on `FieldCheckType` fields.

NOTE: Each document that you store in IDOL Server must contain only one `FieldCheckType` field. If IDOL Server receives a document that contains more than one `FieldCheckType` field, it acknowledges only the first `FieldCheckType` field and ignores the rest.

If you set `UrlAnalysis` to `true` in the IDOL Server configuration file `[Server]` section, you cannot identify a field as a `FieldCheckType` field, as IDOL Server automatically uses the domain it finds in document Reference fields as FieldCheck value.
