Way to prioritize title field for search results?

Can we adjust the Lucene search results so that items most likely to be related are shown closer to the top of the results feed - I'm thinking this would involve providing higher weight to results with matches in a page title field vs. Results with matches in a body field.

There's a bit of plumbing you need in place first. Assuming you're already somewhat familiar with the Content Search API, the core of your question is answered below.
Custom Search Result Item
This is needed in order to access the Title field you are referencing. Example implies a field name of "My Title".
public class CustomSearchResultItem : SearchResultItem
{
[DataMember]
[IndexField("my_title")]
public string Title { get; set; }
}
Search Logic
var index = ContentSearchManager.GetIndex("my index");
using (var context = index.CreateSearchContext())
{
var baseQuery = context.GetQueryable<CustomSearchResultItem>();
var query = PredicateBuilder.True<CustomSearchResultItem>();
if (!string.IsNullOrWhiteSpace(searchQuery))
{
// boost specific search matches
query = query.Or(item => item.Title == searchQuery).Boost(50);
// optionally, split up query to find matches on each word
foreach (var word in searchQuery.Split(' '))
{
query = query.Or(item => item.Title.Contains(word));
}
}
baseQuery = baseQuery.Where(query);
// pagination, etc.
var results = baseQuery.GetResults();
// return results or map to a DTO, etc.
}
What you're mainly after is the Boost
feature. My goto boost is typically 50
and seems to work well.
My main rule-of-thumb is to boost results that are an exact match (even on a content field), and then split the query into individual words for additional results.
Assemblies required:
- Sitecore.ContentSearch.dll
- Sitecore.ContentSearch.Linq.dll

Thanks. When I try this, though, I have a number of complaints from intellisense: containsQuery does not exist in the current context - where is it being defined?

Also query.GetResultss() - 'Expression<Func<SearchHelper.CustomSearchResultItem, bool>>' does not contain a definition for 'GetResults' and no extension method 'GetResults' accepting a first argument of type 'Expression<Func<SearchHelper.CustomSearchResultItem, bool>>' could be found (are you missing a using directive or an assembly reference?)

Just wanted to add that you can not boost wild card queries (aka Contains). So you can never boost the line "query = query.Or(item => item.Title.Contains(word));"
