SDL Fredhopper indexer and query published items sync issue

Question

We have integrated smart target module to one of client. Now we have a issue with fredhopper indexer is not sync with query server.

SDL Version: SDL Tridion 2013 SP1

Smart target version: 2014 SP1

Fredhopper version: fredhopper-7.5-revision-15

Topology.txt
# instance name | host | preset | indexer |  comment
indexer|localhost|1|-|Indexer for staging environment

query|localhost|2|indexer|Query server for staging environment

Issue:

We have found discrepancies between the Indexer and the query server. Meaning, the banner DCP component is successfully published and indexed but is not synced with the query server.

Indexer URL: http://localhost:8180/preview/?fh_location=//catalog01/en_US&preview_seo=false

Total : 383 Items

Searched by published banner dcp component item id : 198118

Results by pass ID (3) :

3 Items: Matched items displayed correctly

Query URL: http://localhost:9180/preview/?fh_location=//catalog01/en_US&

Total : 383 Items

Searched by published banner dcp component item id : 198118

Results by pass ID (3) :

3 Items: Matched but not displayed items in the search area

Kindly advise us to resolve this issue.

It looks like indeed parts of the index are not synced properly.

Probably your best course of action: start with the log files from the "query" instance (fredhopper.log and syncclient.log), and then correlate the events in those with the "indexer" instance (syncserver.log, searchindexer.log, treebuilder.catalog01.log, xmlloader.log).

Also verify that all of these processes are actually running.
