Solr field level search

Question

I'm working on the site search module where the user searches for a particular item.

Currently, the site searches and matches only the item name.

But I'm trying for searching the keyword in item fields also(If any field contains the search value that one also needs to return).

How I achieve this? Is there any API available for this?

Attaching the code.

 var Index = ContentSearchManager.GetIndex("sitecore_" + IndexName + "_index");
 using (var context = Index.CreateSearchContext())
 {
    var allItems = context.GetQueryable<SearchResultItem>().ToList();
    var searchResults = allItems.Where(x => x.Path.ToLower().Contains(pathToBeSearch) && x.Name.ToLower().Contains(searchkey.ToLower())).ToList();
 }

You can search by any field using out of the box functionality. SearchResultItem contains Content field. This field is a computed field and accumulate all text from each item text fields. I adapted your code with one additional condition. See below:

  var searchResults = context.GetQueryable<SearchResultItem>()
.Where(x => (x.Content.Contains(searchkey) || x.Name.Contains(searchkey)) && x.Path.Contains(pathToBeSearch))     
.Where(x => x.Language == ConfigurationItem.Language.Name)     
.Where(x => !excludeTempltes.Contains(x.TemplateName))    
.GetResults().Hits.Select(h => h.Document).ToList();

At the same time, if your site is build using rendering data sources what means that the item content stores not only in the item itself, you might need to search by text in item data sources as well. In this case, you can extend the SearchResultItem.Content field with any texts you want.
