Core Search only yielding results on specific words We've developed a lot of Drupal 7 websites, but never encountered this before (or just didn't notice). When searching the project in question (while having re-indexed the site untill the index is 100%) for a specific word like met it finds a basic page node which contains that word, perfect. Though when looking in the same node and trying the word emissiespectograaf we cannot find the same node nor any other. This goes for a lot of other words, long or short. 

I'm just not getting it, it finds one word in a node but another word, which I know for sure that is in the same node, it's unable to find it. Even though the index has been built for 100%.
Found the culprit after hours of debugging, it seems that the module Features is causing major issues with resetting the Drupal static. See this issue which contains a temporary workaround patch, since this issue has not been resolved with a solid fix yet.
