+==== Index Property Types
+
+ArcadeDB's LSM Tree Indexes can index property fields in various ways:
+
+1. All properties (scalar or collections) can be indexed in a unique or non-unique index (as a whole).
+
+2. An index can be for a single property, or multiple properties in a compund index.
+
+3. String properties can be index tokenized in a full-text index.
+
+4. Object properties can be indexed by keys or by values.
+
+5. List properties can be indexed by values.
+
+6. Vectors of floats can be indexed using a special vector index.
