Hi Alex, As we see, it indexes only words which have a length of 4 characters or more.
The reason is to decrease the total index size (which may in fact not be critical) and to avoid noise like "a", "the" and "and". This function could be made more intelligent. Ahh, that makes sense. I may or may not play around with some changes on a local copy. Might save a newcomer or two some time down the road; not exactly mission critical though.
