# 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
|
||
|
|
`ide::controller::searcher` module.
|
||
|
|
|
||
|
|
### Suggestion Database
|
||
|
|
|
||
|
|
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.
