    How to create Examine AutoComplete ?

    Hi, Good day!

    I would like a autocomplete function with Examine, which should work in a way that when I write "What is" it suggests

    "What is Piering " "What is soil testing" "What is roof sarking?"

    But what I've done is when I write "What is" it suggests all my posts that starts the word "What". See screenshot below.

    enter image description here

    Here is my code;

    [System.Web.Http.HttpPost]
    public List<Article> GetArticles(SearchArticleModel model)
    {
        var result = new List<Article>();
    
        if (!string.IsNullOrEmpty(model.Article))
        {
            var searcher = ExamineManager.Instance.SearchProviderCollection["ExternalSearcher"];
            var searchCriteria = searcher.CreateSearchCriteria();
    
            // Find posts that contain our search text in either nodeName or title
            var searchQuery = searchCriteria.Field("nodeName", model.Article.Boost(8)).Or().Field("title", model.Article.Boost(5)).Compile();
    
            var searchResults = searcher.Search(searchQuery);
    
            foreach (var searchResult in searchResults)
            {
                var articles = new Article()
                {
                    Id = Convert.ToInt32(searchResult.Id),
                    Name = searchResult.Fields["title"],
                };
    
                articles.Url = articles.Id.TypedContent().Url ?? string.Empty;
    
                result.Add(articles);
            }
    
            return result;
        }
    
        return result;
    }
    

    Did I miss something?

    Any ideas or snippet

    Thanks,

    Marky

    Marky,

    Can you write out the generated query I suspect the word 'is' is being stripped out as it is a stop word and you are using standard analyser.

    Regards

    Hi Ismail,

    Thanks for your response.

    I am new in Umbraco, can you tell me how I can generate the query?

    Thanks,

    Marky

    Hi Ismail,

    It might be the query?

    { SearchIndexType: , LuceneQuery: nodeName:what^8.0 title:what^5.0 }
    

    Thanks,

    Marky

    you can see its stripping stop word "is" proof of this can be seen by using luke see image below:

    enter image description here

    I have done auto complete before but matching on single words, it was a combination of building a spellchecker index then doing the auto complete search on that. See on how to build spellchecker index http://blog.aabech.no/archive/building-a-spell-checker-for-search-in-umbraco/ you then have to create an autocomplete analyser that creates ngrams and you then search on that index. I used this stackoverflow post to get to that point https://stackoverflow.com/questions/120180/how-to-do-query-auto-completion-suggestions-in-lucene specifically this part which is c# port of some java code https://stackoverflow.com/a/9183416/719625

    Hi Ismail,

    Here is what I've done, I add MultipleCharacterWildcard() because I read in your post regarding this extension. Link.

    // Find posts that contain our search text in title
    searchCriteria.NodeTypeAlias("StandardContent").And().Field("title", model.Article.MultipleCharacterWildcard()).Compile();
    

    Here is the update query

    { SearchIndexType: , LuceneQuery: +__NodeTypeAlias:standardcontent +title:what is* }
    

    But I got no results.

    []
    

    But here is the data that suppose to be displayed.

    What is Piering?
    What is soil testing?
    What is roof sarking?
    

    But still no luck, and don't know what's the next step.

    Thanks

    Marky,

    Its not wildcard issue, did you take a look at my previous post with links on how to implement autocomplete? Also I only got it working single word.

    Regards

    Hi Ismail,

    Thanks for your reply.

    I haven't read your post regarding on how to implement autocomplete, can you give the link? I really need help for this, since I'm new in Umbraco.

    Can you give me some ideas or what is the exact query to get the whole phrase, because as I read in other blogs that when *symbol is in the last it means, it will show all post that starts whatever you've enter on the search box. e.g. title:foo *

    I'm stuck on this.

    Thanks,

    Marky

    Ohh, Okay.

    This can't be done by using only Examine Search?

    Thanks,

    Hey Ismail,

    Last question, can you tell me where I can create this spellchecker public class SpellCheckIndexer : BaseUmbracoIndexer. I am really new in Umbraco, and I don't know where I can create this stuff.

    Thanks in advance,

    Marky
