Windows search service crashes on indexing

My issue is very similar to the one asked in that question: Windows Service SearchIndexer.exe Crashes on Indexing , however the asker there seems to have abandoned it, hence the repost by me.

Basically, when I check windows error report, I see Windows Indexing crash every 5 minutes. I'm also unable to search my mail in Outlook 2013. I found out about it since wermgr.exe was regularly stealing focus from other applications.

Details of the crash from Event Viewer:

I followed instructions by magicandre1981 from the other thread and got a crash dump, summary below. In case the full dump is needed, I can upload it somewhere.

Alright, so I solved my problem. However, I have no real confidence in that the last step was what truly helped my case, so I'll list all the steps I did in order to get it working again.

• I tried to rebuild search index - didn't help
• Installed Intel Rapid Storage driver - no change
• Ran chkdsk on both hard drives - didn't help
• Unchecked the box to permit indexing on C: drive and subdirectories, and then checked it again - didn't help
• Removed from indexing options in control panel every entry but "Microsoft Outlook" and "Favorites" and then rebuilt the index again - seemed to somewhat help for a moment, but stopped working again promptly (no search in Outlook, but also the error reports stopped coming)
• Disabled Cached Exchange Mode for my account in Outlook - search seems to work again, not breaking for one day straight now.

Not sure if this is helpful to future visitors, since I didn't identify the root cause, but as of now the Outlook search is working and I'm satisfied. Thanks for all the suggestions in the comments.
