I have this code snippet that is working fine:

ISearchCriteria query;

query = searcher.CreateSearchCriteria(BooleanOperation.Or)
 .Field("IsProtected", "false")
    .Or()
 .GroupedAnd(new string[] { "IsProtected", "AccessRoles" }, new string[] { "true", "Staff" })
  .And()
    .GroupedOr(new string[] { "pageTitle", "pageHeading", "pageIntroduction", "bodyText" }, Query)
    .Compile();

But I need to dynamically add more than one GroupedAnd method outside of the fluent "one liner". I.e:

ISearchCriteria query;

query = searcher.CreateSearchCriteria(BooleanOperation.Or)
 .Field("IsProtected", "false")
    .Or()
 .GroupedAnd(new string[] { "IsProtected", "AccessRoles" }, new string[] { "true", "Staff" });

query.Or()
   .GroupedAnd(new string[] { "IsProtected", "AccessRoles" }, new string[] { "true", "Partner" });

query.And()
    .GroupedOr(new string[] { "pageTitle", "pageHeading", "pageIntroduction", "bodyText" }, Query)
    .Compile();

I know this isn't going to work, but hopefully you get what I'm trying to do. Do I need to do something with IQuery? I can't find any code examples on how to deal with spreading the generation of the query across more than one fluent "one liner".

Solved it. Turns out I needed to use the IBooleanOperation type to build the query, e.g:

var searcher = ExamineManager.Instance.SearchProviderCollection["SiteSearchContentSearcher"];

IBooleanOperation query = searcher.CreateSearchCriteria(BooleanOperation.Or).Field("IsProtected", "false");

Then append to that query, e.g:

foreach(string role in Roles.GetRolesForUser())
{
    query = query.Or().GroupedAnd(new string[] { "IsProtected", "AccessRoles" }, new string[] { "true", role });
}

Then, finally, do the search, e.g:

var results = searcher.Search(query.Compile());

In case this helps someone else... Or me if I forget this in another 6 months... :-)
