The problem is probably the problem I think I'm having now. I disable 'static' in the search index, but enable 'contentblock' thinking this will only search the content blocks in the pages and not the surrounding text (ie, template stuff). What I do to fix this (unfortunatly) is click 'share' on the content blocks to make them show up in the 'content blocks' under modules.
So, just curious, is this intended? It appears that only 'shared content blocks' are search and not content blocks in pages. If this is the case, change the option for the search index from 'content blocks' to 'shared content blocks'. or rename the content blocks that are in pages but not shared.... bit confusing.
