Searching data based on processing node map identifiers

A computing system of a data intake and query system, the computing system comprising:

• memory;
• and
• one or more processors coupled to the memory and configured to:
• receive, at a search node of a plurality of search nodes of a query system, a processing node map identifier from a search head of the query system, wherein the processing node map identifier is received in response to a query received by the query system, wherein the query includes filter criteria to identify a set of data and processing criteria that indicates how to process the set of data;
• identify a plurality of data identifiers based on the processing node map identifier included in a cache, wherein the plurality of data identifiers includes a first set of data identifiers received from a node coordinator and a second set of data identifiers generated by the search node;
• identify a plurality of data groups assigned to the search node based on the plurality of data identifiers, wherein a particular data identifier of the plurality of data identifiers identifies a particular data group of the plurality of data groups;
• apply at least a portion of the filter criteria from the query to identify a set of data groups of the plurality of data groups to search;
• and
• search the set of data groups based on the query.

Non-transitory computer readable media comprising computer-executable instructions that, when executed by a computing system of a data intake and query system, cause the computing system to:

• receive, at a search node of a plurality of search nodes of a query system, a processing node map identifier from a search head of the query system, wherein the processing node map identifier is received in response to a query received by the query system, wherein the query includes filter criteria to identify a set of data and processing criteria that indicates how to process the set of data;
• identify a plurality of data identifiers based on the processing node map identifier included in a cache, wherein the plurality of data identifiers includes a first set of data identifiers received from a node coordinator and a second set of data identifiers generated by the search node;
• identify a plurality of data groups assigned to the search node based on the plurality of data identifiers, wherein a particular data identifier of the plurality of data identifiers identifies a particular data group of the plurality of data groups;
• apply at least a portion of the filter criteria from the query to identify a set of data groups of the plurality of data groups to search;
• and
• search the set of data groups based on the query.
