How to search a pattern and fold the matching lines

Hi ,

I want to fold set of lines after search as follows,

> The mouse can also be used to open and close folds by following steps:

Click on a '+' to open the closed fold at this row.

Click on any other non-blank character to close the open fold at this row
>



I want to search click and collapse all matching lines.

> The mouse can also be used to open and close folds by followingsteps:

+--

There is a method to collapse the patterns which are not matching in vim , after searching a pattern we can collapse non matching patterns by "\z" key .

``` nnoremap \z :setlocal foldexpr=(getline(v:lnum)=~@/)?0:(getline(v:lnum-1)=~@/)\\|\\|(getline(v:lnum+1)=~@/)?1:2 foldmethod=expr foldlevel=0 foldcolumn=2<CR>
```

Is there any option to do the opposite? Just find a pattern and collapse?
