We’ve been investigating reports that BPM search and Task guide help are broken.
The root cause is that our task guide search indexing mechanism at times will delete some entries from an index during index maintenance. This had been known to happen very intermittently, and we had been mitigating this by re-indexing individual task guide libraries. Recently after some scale out work to improve search performance, however, this has gotten much worse. As of last week, search against our global task guide libraries had stopped working altogether, both in the LCS client as well as from the Help pane in the web client.
We hope to have an initial fix that stops the index process from deleting entries available to deploy to LCS by early next week. In the meantime, we plan to re-index the global task guide libraries today to reenable search of those libraries. Additionally, we are actively working on longer term fixes to avoid the indexing problems in the future.
