# Store and Retrieve the Result State

Whenever you use the `Query`, `Suggest`, or `SuggestOnText` actions, you can save the result state (the `DocID` values of all returned results) in a state token. In subsequent actions, you can use this token to represent the documents from that result set.

A state token is an array of `DocID` values. Its name is of the form `ABCDEFGH–N`, where `ABCDEFGH` is a random alphanumeric string (generated at query time), and `N` is the number of document IDs that the token holds. You can also use document references, rather than document IDs, to create state tokens. In this case, use the `StoredStateField` parameter to specify the name of the field that contains the references.

When you have a state token, supply the token name to specify the entire set of documents (for example, `CWQ4FJ9LZSE5-6`). You can also use a (zero-based) array notation to specify a subset of the documents (for example, `CWQ4FJ9LZSE5-6[3]` to select the fourth document in the array).

Tokens in the array are in the same order as in the returned results.

HPE IDOL Server stores tokens persistently, in the directory `installDir/agentstore/storedstate`.
