db.Tables.Where(c=>c.Fullname.Contains(text)); var text = FullTextSearchModelUtil.FreeText("code ef");
db.Tables.Where(c=>c.Fullname.Contains(text)); var text = FullTextSearchModelUtil.ContainsAll("code ef");
db.Tables.Where(c=>c.Name.Contains(text)); //c.Name could be any string property of model var text = FullTextSearchModelUtil.FreeTextAll("code ef");
db.Tables.Where(c=>c.Name.Contains(text)); //c.Name could be any string property of model var text = FullTextSearchModelUtil.Contains("a b",true);
var query = db.TestModel.Where(c => c.Name.Contains(text)).ToList();
// Should return results that contain BOTH words. For the second param = false, should return records with either of the wordsMulti field query
var query = db.TestModel
.Where(c => (c.Name+c.Text).Contains(text))
.ToList();will generate the sql
