Sorry, I meant to ask

Are you sure "key1" has TEXTSTRING mapping, rather than TEXT mapping?

For these kind of queries you need TEXTSTRING mapping. As an alternative you can create composite index to "equals" queries

Do we need reindexing even for properties created after index?

Thanks for the explanation. I noticed your example code contains the following snippet:

                janusgraphIndex = mgmt.getGraphIndex(VERTEX_INDEX_NAME)

                mgmt.addIndex(janusgraphIndex, propertyKey)

I don’t have a computer with me right now, but IIRC there is no “addIndex” API. Do you mean by “addIndexKey”?

Another question: let’s say you create a new mixed index with property A. Later, you add a new property B to it using “mgmt.addIndexKey” API. Then you create a vertex with both property A and property B. Now, are you only able to leverage the mixed index to query property A only, but not property B? Also, what new document(s) do you observe on ES? A concrete example would be greatly appreciated if possible.

Hi Boxuan,

Thanks for the quick response. Actually, I'm following a strict schema in my service. 

i.e we first register a schema and then use it for vertex/edge creation.

So I'm not creating schema and vertex/edge in the same transaction. Only property key and index creation are happening in one transaction that is also at starting of the service only. From next time is index already exists then my service adds new properties to it.

These new properties are created after the creation of the index in a separate transaction are visible in management API printIndexes and printSchema. Also, they are visible in elastic mapping.

You said you were able to create index, add vertices and edges, and query them utilizing index in the same transaction, but not in a new transaction. Can you give complete code examples that demonstrate how you do so in the same transaction AND in a new transaction, as Marc asked? Specifically, do include how you open and commit/rollback transactions.

In addition, I wonder if this always happens no matter how long you wait, or only happens in a short period of time. Schema propagation takes some time, and you may see a sync delay across JanusGraph instances. If you create the index on one JanusGraph instance, and immediately insert & query data in another JanusGraph instance, it might be the case that schema propagation is not done yet and your other JanusGraph instance is not aware of the recently created index.

Another thing you could check is the Elasticsearch. After creating the index, do you see the index on your ES cluster? After inserting vertices/edges, do you see documents created at ES side?

Specifically, do include how you open and commit/rollback transactions.

In addition, I wonder if this always happens no matter how long you wait, or only happens in a short period of time. Schema propagation takes some time, and you may see a sync delay across JanusGraph instances. If you create the index on one JanusGraph instance, and immediately insert & query data in another JanusGraph instance, it might be the case that schema propagation is not done yet and your other JanusGraph instance is not aware of the recently created index.

Another thing you could check is the Elasticsearch. After creating the index, do you see the index on your ES cluster? After inserting vertices/edges, do you see documents created at ES side?

Sorry I misread your email. I thought you were using TEXT mapping only.

You said you were able to create index, add vertices and edges, and query them utilizing index in the same transaction, but not in a new transaction. Can you give complete code examples that demonstrate how you do so in the same transaction AND in a new transaction, as Marc asked? Specifically, do include how you open and commit/rollback transactions.

In addition, I wonder if this always happens no matter how long you wait, or only happens in a short period of time. Schema propagation takes some time, and you may see a sync delay across JanusGraph instances. If you create the index on one JanusGraph instance, and immediately insert & query data in another JanusGraph instance, it might be the case that schema propagation is not done yet and your other JanusGraph instance is not aware of the recently created index.
