Immediately, when you open Flex Search, you should be presented with a large grid of search engine icons. Simply tap one of them to start searching from that engine.
When changing queries, you can access this engines list by tapping the current engine's icon in the top left. Or if you are in a search result page, you can hold the magnifying glass button in the top left to see this list of engines.
In the query box of the main page, you should find a microphone icon. Tap it and start speaking; the app will detect when there is no more sound.
Since the reason to use this app is to search online engines quickly, we decided that it would be redundant to build an offline recognition system, so no, you cannot use voice recognition offline.
In the search result page, tap the gear in the top right.
In the current version of Flex Search, no you can't add your own engines. However we plan to add this feature in a future update.
If you are a developer and want a search engine to be included, feel free to contact us and we will consider it for inclusion.
