# Knowledge Discovery Actions

If you are running the DAH in mirror mode, it can distribute all Knowledge Discovery actions to its child components. If you are running it in non-mirror mode, it can only support the following Content component actions:

`DetectLanguage` | `Query`
`DocumentStats` | `Suggest`
`GetContent` | `SuggestOnText`
`GetQueryTagValues` | `Summarize`
`GetTagNames` | `TermExpand`
`GetTagValues` | `TermGetBest`
`Highlight` | `TermGetInfo`
`LanguageSettings` |

For the `LanguageSettings` action, when the child servers have compatible language configurations, DAH returns the child server response, except for the `LanguageDirectory` configuration. The child server language configuration must be the same for all child servers, except for `LanguageDirectory`. If the child server configuration is not compatible, DAH returns the message `Engines returned inconsistent information`.

For details about Content component actions, refer to the Content Component Help.

NOTE: In non-mirror mode, you cannot use Content action parameters that contain IDs of documents. Use document reference instead. In addition, the following action parameters are not supported:

- `DontMatchID`

- `MatchID`

- `MaxID`

- `MinID`

- `Cluster`

- `Delete`

- `UseVectors`
