RE: Incremental search don't append wrongly typed characters

I don't have a better answer for you - perhaps someone else does.
 
But I think that what I described: a key that deletes the mismatched portion,
might actually solve your problem of searching within a keyboard macro. When
defining the macro, you could presumably just hit that key when typing the
search string is "done".  If there is no mismatched portion for a given search,
then the key would do nothing.
 
However, the interactive part of using your macro wrt searching is not really
clear to me. So maybe I'm missing something.
 
Anyway, such a key does not exist yet, but if I get some time I'll try to come
up with it. Or perhaps someone else (you?) will beat me to it.  Look in
isearch.el for the part of the code that identifies the mismatched portion for
highlighting, or the part of `isearch-edit-string' that moves the cursor to the
mismatch beginning.
 
HTH.


Drew, thanks for the answer. Unfortunately I need a different behavior in my
particular case. I was proposed with similar work-around also on stack overflow.
Though, I'm often using incremental search for query specific tags in a large
text file which is used like database system with help of some configuration and
scripts. Before each incremental search there is a macro which places me to BOF
and afterwards starts incremental search. For this scheme it would be very
convenient just not to append mismatched part at all. I understand that it's not
that standard feature and I use different approach when let's say coding or
typing text but again for this particular case I need the mentioned behavior. It
will save me some additional clicks to backspace and/or c-s  c-g. In other
words: I'm  looking for a way of not showing mismatched characters during
incremental search. Thanks a lot for your time.

I don't have an answer for you, but the suggestion is an interesting one.

A variant that could be useful (which I also don't have a recipe for):

Type `keyz'.
The `z' is highlighted as a mismatch (this is already available).
Hit a key to delete the mismatched part (in this case, just `z'.
Type `s' and continue.

When I introduced highlighting of the mismatch part, I took it from Icicles
highlighting of completion input mismatch.  There, you can hit `C-l' twice to
remove the mismatched part.  (The first `C-l' just moves the cursor to the
mismatch beginning, so you can insert there.)

In Isearch there is no equivalent - no key that removes the mismatched part.
Maybe I'll add that possibility.  What you can do is hit `M-e', which puts you
in editing mode and moves the cursor to the mismatch beginning.  Then hit `C-k'
to kill the mismatch portion, then `C-s' to resume searching.  So `M-e C-k C-s'.
