# Search & Filters

### Server-side vs Client-side filters

Filters on Database Connected Data Sources are Server-side. Also, read objects (from Database) with some filter is done Server-side. *All other filters are Client-side, and performed in your browser.* Read more in the article below.

**Article**:

* [Server-side vs Client-side filters](https://docs.appfarm.io/appcademy/appfarm-professional/data-structures-and-data-handling/pages/-MiR9GGOxcZeghNQPbzV#server-side-vs.-client-side-filters)

### Filter/search with String operators

A special set of operators exists when you set up a Filter with a string as the left operand. This can be used to implement search. The operators may also be used for Conditions.

**Article**:

* [String operators](/reference/platform-concepts/operators.md#string-operators)

**Example in Showroom:**

* See "[Expandable Search Pane](https://showroom.appfarm.app/ui-components/motions)" of the Motions example for usage for the `Contains` operator through a Read Objects.
