1) Just thinking it would be useful for the search result to show at least one part of the post with the word searched for, not an excerpt of the first part that may not show the word(s). The searched for word may be well down in page 13 of the post making it difficult to find.
Once the 'word' has been found it's position needs to stored and then, some text displayed starting with the preceding higher case letter to indicate the start of a sentence; (and the page number if a post with multiple pages).
EDIT I suppose this 'dynamic' search could/would take a long time as all combinations of words could hardly be stored for quick access ?
Some feedback on this would be nice
2) Can there be more than one collection to be searched
