Are there specific procedures for creating an index to be used when running an embedded file-based client? My question arises out of unit tests on a simple client created as shown at the ES client page. It will successfully index a document, then immediately read it back. But, when I open that client again to read it later, that index is null. When I create a node, to get the client and give it a data path, etc, then use the client on a named index, I'm guessing that doesn't create the named index, even though I see data in folders. What am I missing? Many thanks in advance. Jack -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

An update: I found some code which tests for existence of an index and creates it if it is not there. I now see this message: NoShardAvailableActionException: [testindex][0] null even though the index is there and it is not locked. Testing works this way: One unit test creates a document then reads it back then closes the node and client. Second unit test simply goes back and reads the document, resulting in that error. But, if I run in debug mode (Eclipse), and walk the second unit test through, it reads the document with no errors. My reading routing allows for 10 seconds in its get() as follows: GetResponse resp = client.prepareGet(idx, typ, documentId).get("10000"); Confusing why walking through the code slowly allows success, but running directly does not.

A fix was discovered in a message by David Pilato earlier with a link to this: > which appears to have resolved my issues. The context of my query is specifically that of a local, embedded Client using a file-based index. Answer to my opening question appears to be simply this: look to see if your indexes are created by following APIs in AdminClient; if not, create them. But, before you do that, create the node, then client, then use that test suggested above to wait for the Client to settle.
