A Firestore index covering multiple fields to enable compound queries.
فهرس Firestore يغطي حقولًا متعددة لتمكين الاستعلامات المركبة.
Full Definition
A Composite Index in Firestore allows queries that filter or sort on multiple fields simultaneously. Without a composite index, Firestore will throw an error on multi-field queries. Indexes are defined in firestore.indexes.json and deployed via Firebase CLI.
الفهرس المركب في Firestore يسمح بالاستعلامات التي تفلتر أو ترتب على حقول متعددة في آن واحد. بدون فهرس مركب سيُظهر Firestore خطأ. يُعرَّف الفهرس في firestore.indexes.json ويُنشر عبر Firebase CLI.
Example Usage
“Query: where('status', '==', 'published').orderBy('createdAt', 'desc') requires a composite index on (status ASC, createdAt DESC).”
