> In fact, I'm pretty sure any competitive search engine these has to have a very complex crawler that is more than able to deal with javascript rendered pages.

Save the region-specific engines which likely lag behind, Google [0] and Bing [1] both support crawling javascript, and Bing is generally the search engine index of choice for all other search engines like Yahoo, DDG (at least for now, I occasionally get crawls from duckduckgobot), etc.
