+
+#### Modulus Query
+
+When using a modulus query, you must supply the divisor and the remainder. For example, to obtain all likes which are multiples of 100, you would specify a divisor 100 and a remainder 0:
+
+```shell
+curl -X GET http://localhost:3000/db/docstore/query -H "Content-Type:application/json" --data '{"propname":"likes", "comp":"mod", "values":[100,0]}'
+```
+
+```json
+[{"site":"https://ipfs.io","likes":400,"project":"IPFS"},{"site":"https://github.com/orbitdb/orbit-db","likes":200,"project":"OrbitDB"}]
+```
+
+#### Range Query
+
+When specifying a range query, you must supply the min and max
+values. For example, to obtain all likes greater than 250 but less than 1000 the min and max must be supplied:
+
+```shell
+curl -X GET http://localhost:3000/db/docstore/query -H "Content-Type:application/json" --data '{"propname":"likes", "comp":"range", "values":[250,1000]}'
