@ -54,7 +54,7 @@ Search and replace
The Bulk metadata edit dialog allows you to perform arbitrarily powerful search and replace operations on the selected books. By default it uses a simple text search and replace, but it also support *regular expressions*. For more on regular expressions, see :ref:`regexptutorial`.
As noted above, there are two search and replace modes: character match and regular expression. Character match will look in the `Search field` you choose for the characters you type in the `search for` box and replace those characters with what you type in the `replace with` box. Each occurance of the search characters in the field will be replaced. For example, assume the field being searched contains `a bad cat`. if you search for `a` to be replaced with `HELLO`, then the result will be `HELLO bHELLOd cHELLOt`.

If you search for `a` to be replaced with `HELLO`, then the result will be `HELLO bHELLOd cHELLOt`.
If the field you are searching on is a `multiple` field like tags, then each tag is treated separately. For example, if your tags contain `Horror, Scary`, the search expression `r,` will not match anything because the expression will first be applied to `Horror` and then to `Scary`.
