I am working on an Examine search that has a free text field and then some additional filters (which are in the form of checkbox lists). The problem I have is trying to get the additional filters to work.

I am passing through separate string lists of filters, if more than one filter option is selected then it should show results that match either of those filters.

For example, if filter 1 has five options as follows:

• A
• B
• C
• D
• E

And both "B" and "D" are selected it should return results where "property1" is either "B" or "D" as well as matching on the free text search.

This is what I have so far but it does not work (it just returns all results), can anyone point me in the right direction:

if (searchTerm != string.Empty) {

var fields = new[] {"nodeName", "heading1", "summary", "mainText"};
var term = new IExamineValue[] {searchTerm.ToLower().Escape()};

// Setup query
query = searchCriteria.GroupedOr(fields, term);

if (filters1.Any())
{
    query.And();
    foreach (var x in filters1)
        query.Or().Field("property1", x);
}

if (filters2.Any())
{
    query.And();
    foreach (var x in filters2)
        query.Or().Field("property2", x);
}

// Run search query
var searchResults = searcher.Search(query.Compile());

}
