Description

An enumeration that contains the available search engine scopes.

A search engine scope identifies where a search comes from. This is useful when implementing a single entry point for the base engine functions:

using System;
using System.Collections.Generic;
using System.Linq;
using UnityEditor;
using UnityEditor.SearchService;
using UnityEngine;
using Object = UnityEngine.Object;

class BaseEngine : ISearchEngineBase { public virtual void BeginSession(ISearchContext context) { if (context.engineScope == ObjectSelector.EngineScope || context.engineScope == Project.EngineScope) { // Cache Assets. } if (context.engineScope == ObjectSelector.EngineScope || context.engineScope == Scene.EngineScope) { // Cache Scene objects. } }

public virtual void EndSession(ISearchContext context) { // Flush any cached data. }

public virtual void BeginSearch(ISearchContext context, string query) { }

public virtual void EndSearch(ISearchContext context) { }

public string name => "My Engine Service"; }

[SceneSearchEngine] class SceneFilterEngine : BaseEngine, ISceneSearchEngine { public bool Filter(ISearchContext context, string query, HierarchyProperty objectToFilter) { // Use cached Scene objects. // ... return true; } }

[ProjectSearchEngine] class ProjectSearchEngine : BaseEngine, IProjectSearchEngine { public IEnumerable<string> Search(ISearchContext context, string query, Action<IEnumerable<string>> asyncItemsReceived) { // Use cached Assets. // ... return new List<string>(); } }

[ObjectSelectorEngine] class ObjectSelectorEngine : BaseEngine, IObjectSelectorEngine { public bool SelectObject(ISearchContext context, Action<Object, bool> onObjectSelectorClosed, Action<Object> onObjectSelectedUpdated) { // Use cached Assets and Scene objects. return true; }

public void SetSearchFilter(ISearchContext context, string searchFilter) {} }

Properties

SceneIdentifies a search for Scene engines.
ProjectIdentifies a search for Project engines.
ObjectSelectorIdentifies a search for ObjectSelector engines.
