# Searcher Panel In Graph Editor
|
|
|
|
|
|
|
|
|
|
### Behaviour
|
|
|
|
|
|
|
|
|
|
The Searcher Panel can be brought to the screen in two different ways:

|
|
|
|
|
|
|
|
- when user starts to edit node's expression - the node becomes Searcher input
|
|
|
|
|
and panel appears below,
|
|
|
|
|
- when user press tab with mouse over Graph Editor Panel - the new Searcher
|
|
|
|
|
input appears with Searcher panel below. Additionally, if there is exactly one
|
|
|
|
|
node selected, the connection is displayed between the selected node and the
|
|
|
|
|
Searcher input.

### Suggestion of Node Expressions
|
|
|
|
|
|
|
|
|
|
The suggestion list is obtained from the Engine using `search/completion` method
|
|
|
|
|
of Language Server. The parameters of the call depend on the Current searcher
|
|
|
|
|
input, suggestions picked suggestions so far, and if we are adding a node
|

|
|
|
connected to selection. The current implementation can be found in
|
2020-07-16 10:50:31 +03:00
|
|
|
`ide::controller::searcher` module.
|
|
|
|
|
|
|
|
|
|
### Suggestion Database
|
|
|
|
|
|
2021-11-05 14:51:43 +03:00
|
|
|
The `search/completion` method of Language Server returns a list of keys to the
|
|
|
|
|
Suggestion Database instead of the whole entries. The database is retrieved by
|
|
|
|
|
IDE on Project opening, and keeps it up to date. The Database is implemented in
|
|
|
|
|
`ide::model::suggestion_database` module.
