Safari text search must begin with first letter, bug?

I just noticed this recently while I searched a page I was visiting, which made no sense that Safari returned no results. Then I realized this is what happens when I don't start the search with the first character.

Just now as I was trying to do screen capture for this thread, I see that if searching for a number that is preceded by a letter, it will find it, but not if it's preceded by another number

I captured 4 shots to show you what I mean. Is there something I'm missing or this is in fact a bug? I searched Google and found no complaints about this.

PS I updated to OSX 10.8.4 and Safari 6.0.5 this morning, but it was already happening before the update.

 

I think this is deliberate, rather than a bug. I'm not sure why it would be cause for concern.

 

No other browser behave this way when searching for text. If this is by design it makes no sense. Like I said I found this out when I knew it made no sense that Safari returned "not found" when I know the data I was searching for is in there, but I only had a partial search string. The way it is, I can't use Safari for some of the work I perform.

 

I find it makes much more sense, to be honest. The behaviour of other browsers in this respect irritates me.

 

It does the same thing with letters... it doesn't do partial matches on words or numbers.

just like searching this page....

15001 ... if you search for 500, it should not find a 500 in 15001 ... because its not 500.

Restore ... if you search for store, it will not find the store in restore, as its not the word store. Most other browsers at default settings will find these types of things.

 

looks like a design bug to me. I find that annoying. If I'm presented with a functionality called text search, I want it to search the text for that string, not words starting with that string.
