The Query Engine determines\n * what mode to use based on what data is persisted. The mode only determines\n * the runtime complexity of the query - the result set is equivalent across all\n * implementations.\n *\n * The Query engine will use indexed-based execution if a user has configured\n * any index that can be used to execute query (via `setIndexConfiguration()`).\n * Otherwise, the engine will try to optimize the query by re-using a previously\n * persisted query result. If that is not possible, the query will be executed\n * via a full collection scan.\n *\n * Index-based execution is the default when available. The query engine\n * supports partial indexed execution and merges the result from the index\n * lookup with documents that have not yet been indexed. The index evaluation\n * matches the backend's format and as such, the SDK can use indexing for all\n * queries that the backend supports.\n *\n * If no index exists, the query engine tries to take advantage of the target\n * document mapping in the TargetCache. These mappings exists for all queries\n * that have been synced with the backend at least once and allow the query\n * engine to only read documents that previously matched a query plus any\n * documents that were edited after the query was last listened to.\n *\n * There are some cases when this optimization is not guaranteed to produce\n * the same results as full collection scans. In these cases, query\n * processing falls back to full scans. These cases are:\n *\n * - Limit queries where a document that matched the query previously no longer\n * matches the query.\n *\n * - Limit queries where a document edit may cause the document to sort below\n * another document that is in the local cache.\n *\n * - Queries that have never been CURRENT or free of limbo documents.\n */\nclass __PRIVATE_QueryEngine {\n constructor() {\n this.Zi = !1, this.Xi = !1, \n /**\n * SDK only decides whether it should create index when collection size is\n * larger than this.\n */\n this.es = 100, this.ts = \n /**\n * This cost represents the evaluation result of\n * (([index, docKey] + [docKey, docContent]) per document in the result set)\n * / ([docKey, docContent] per documents in full collection scan) coming from\n * experiment [enter PR experiment URL here].\n */\n function __PRIVATE_getDefaultRelativeIndexReadCostPerDocument() {\n // These values were derived from an experiment where several members of the\n // Firestore SDK team ran a performance test in various environments.\n // Googlers can see b/299284287 for details.\n return isSafari() ? 8 : __PRIVATE_getAndroidVersion(getUA()) > 0 ? 6 : 4;\n }();\n }\n /** Sets the document view to query against. */ initialize(e, t) {\n this.ns = e, this.indexManager = t, this.Zi = !0;\n }\n /** Returns all local documents matching the specified query. */ getDocumentsMatchingQuery(e, t, n, r) {\n // Stores the result from executing the query; using this object is more\n // convenient than passing the result between steps of the persistence\n // transaction and improves readability comparatively.\n const i = {\n result: null\n };\n return this.rs(e, t).next((e => {\n i.result = e;\n })).next((() => {\n if (!i.result) return this.ss(e, t, r, n).next((e => {\n i.result = e;\n }));\n })).next((() => {\n if (i.result) return;\n const n = new QueryContext;\n return this._s(e, t, n).next((r => {\n if (i.result = r, this.Xi) return this.us(e, t, n, r.size);\n }));\n })).next((() => i.result));\n }\n us(e, t, n, r) {\n return n.documentReadCount < this.es ?
