<p>The <code>query</code>-parameter should be interpreted in a <em>relaxed way</em> as the editor will apply its own highlighting
|

and scoring on the results. A good rule of thumb is to match case-insensitive and to simply check that the

characters of <em>query</em> appear in their order in a candidate symbol. Don't use prefix, substring, or similar
|

strict matching.</p>

<p>To improve performance implementors can implement <code>resolveWorkspaceSymbol</code> and then provide symbols with partial
|
|
|
<a href="../classes/SymbolInformation.html#location">location</a>-objects, without a <code>range</code> defined. The editor will then call
|
|
|
<code>resolveWorkspaceSymbol</code> for selected symbols only, e.g. when opening a workspace symbol.</p>
