How to use specific dataset in case of multiple dataset in datamodel ?

Hello,

In our datamodel, we have multiple datasets (root events/ root search).
But only the 1st one is working in the tstat search.

In below example I have 3 datasets, only SERVICE dataset is working, if I remove SERVICE then BA_LIVEBOOK will work and if remove BA_LIVEBOOK as well then RISKENGINE will work.

Below search query is to access BA_LIVEBOOK dataset but it will work only if I remove SERVICE EVENT.
Is there a different way of access in case of multiple datasets?

| tstats values(BA_LIVEBOOK.NPID) as NPID FROM datamodel=SERVICE_V7 WHERE (nodename=BA_LIVEBOOK) GROUPBY source

Hi @agoyal,

What are the populating searches for your root events/searches ?

If they are independent I would advise you to go ahead and build a separate DM for each of the root searches, a general rule of thumb would be to have a root search and then child searches to get the best performance and avoid the kind of issues you're having.

Cheers,
David,

data in different dataset are related but queries are different. I can't use as parent/child because I am using "|" in constraint which is not allowed in child. we have 4 datasets now and may get increase later. Managing would be eaiser to have single datamodel.

Anyway, My consern is If there is option of having mutliple datasets then I don't understand why we can't use like this. May be I am missing some property which require to call the dataset in search query.
