Google has removed many pages from my site out of index. Is everyone else witnessing the same?

Yes. Google seems not to index, or did not crawl for 2-3 months some pages.
If those are deep internal pages that's fine I'd say. They seem to emphasize on some freshness type of factors indpendently of true (human) value of pages.
Let's remind Google that the web is not a giant newspaper and 99.9999% of blogs are not USAtoday, not even close.

In my opinion this participates to the whole weird and confused spammy indexed, half in japanese that we can spot on many low and average volume of searches.

They also some serious resource issues in my opnion. They could have been forced to draw part of their computer power to a point where they have to choose to emphazise more on freshness instead of freshness being just a regular factor as before when SERP's where still no so insane...a few weeks ago.

I've performed more search tests during a business trip yesterday, i was bored.
Well I very much think so that the singular plural change issue, yes it's an issue at multiple levels, also came in with a few keyword stemming changes.
This part, a former Google super strengh allowed document retrieval contributed to increasing averall value on page 1.

These would participate sldo to the feeling of: "WTH is going on LOL" I have every single search I make for the past weeks.

A whole part of the site-theme-query association is not making it to Google's top layer algo, not even remotely.
I still did not find one of the newly surprising sites have brought any quality to the result at all.

It's been a few months that Google does weird things.
We should have warmed them before, hope it's not too later sincenrely.
