INSTALL.txt in Search and Replace Scanner 5.2

Scanner Search and Replace
--------------------------

BEFORE YOU START:

Backup your database!  Scanner Search and Replace is a very powerful tool, and 
as such is very dangerous.  You can easily destroy your entire site with it.  Be 
sure to backup your database before using it.  No, really.


I. INSTALATION:

1. Place the entire scanner folder in your modules directory.

2. Go to [administer -> site building -> module] and enable the scanner module.

3. Go to [administer -> user management -> access control] and apply your 
preferred access settings to the scanner module.  You can set which roles can 
administer the module -- e.g., determine which fields can be scanned and modify 
defaults -- and which roles can use the module.  This is is handy if, say, you 
only want the site admin to administer the module, but you want content 
managers to be able to perform search and replace actions.

4. Go to the Scanner administration panel and select which fields you want to 
include in search and replace actions. More information on that is available 
below in the Administration Options section.


II. ADMINISTRATION OPTIONS:

You can access the Scanner admin panel two ways:

1. Go to [administer -> site configuration -> search and replace scanner].
2. Go to [administer -> content management -> search and replace scanner] and 
select the "Settings" tab.

A. Fields that can be searched:

The most important part of administering Scanner is making sure you select one 
or more options in the "Fields that can be searched" section.  Fields are listed 
in [nodetype: fieldname] format.  If you only want to allow  people with access 
to search and replace on the Body field of the Page content type, 
select [page: body].

Teasers are a special case, because they are built off the body and other 
fields.  Most Scanner admins will likely not select any teaser fields in 
this section, and will use the "Rebuild Teasers on Replace" option (under the 
"Scanner Options" section) instead.  This option automatically rebuilds teasers 
to reflect any changes in other fields for a given node.

However, some admins may want not want to update teasers or may want to limit teaser updates to specific content types.  In the latter case, you select one or more of the [nodetype: teaser] options in the "Fields that can be searched" section.

B. Scanner Options:

In this section, you can set the defaults for several search options that 
Scanner users will see when they use the search and replace form.  Users will 
still be able to change the options on their own, but the defaults can make 
things easier for them if they're likely to only perform one kind of search most of the time.

You can also select whether teasers for nodes should be rebuilt after a 
replacement has been made to the body or other fields for that node.  Most 
admins will select this option, because it ensures that teasers are in synch 
with node content.  But see section II.A above for more info on why leaving 
this option unselected might be helpful.

If your site has categories set up in the Taxonomy module, you can restrict 
search and replace actions to nodes that contain terms in a given category 
(a.k.a "vocabulary").  Select the vocabularies that you want to allow 
restricting by.  When users go to the search and replace form, they will have 
the option of selecting one or more terms from those vocabularies for limiting 
their searches.

C. Custom Fields:

Note: This feature has not been thoroughly tested in Scanner 2.  However, it 
was designed to let admins specify additional fields for search and 
replace that may not have shown up automatically in the "Fields that can be 
searched" section.  Enter only one field per line, in the following format:

  [fieldname] in [tablename] of type [nodetype] on [vid|nid]

If you try this, please please please be sure to backup your database first 
(as you should before you use this module anyway) -- and let us know your 
feedback!
