8/25/2023 0 Comments Solr typeaheadThe suggester also supports weights - while wildcards wouldn't really do that in a proper way. The suggester component supports many different configuration options to get the behavior you want, as well as (for some backends) context filtering (which would be easier to implement with just a wildcard, since it'd be a regular fq). That's the reason why the suggester was implemented. So it works - kind of - but it's not ideal. And since you don't have any analysis taking place - if you'd have indexed men's (which would be processed to match just men as a single token in most cases), and searched for men's* - you wouldn't get a hit. In your example with a leading wildcard, the query will also be very expensive - since it will require Lucene (Solr's underlying search library) to in effect look at each generated token and see if somewhere inside that token there's the text mob. You can work around this with the ComplexPhraseQuery, but that might not be what you're looking for (and can get expensive in regards to the number of terms quickly). The problem is that when you're querying with wildcards, the analysis chain is not invoked (a bit of a simplification - most filters are not invoked, only those that are MultiTermAware) - so as soon as you type a space, you're out of luck.

You will need to add a new dynamic field: You will need to update the Solr schema file so that Solr can apply the NGram analyzer to the new datatype. Update the Solr schema to support the new data type If (String.Compare(, "core", StringComparison.OrdinalIgnoreCase) = 0)ĭon’t forget to add this field to the Sitecore Solr config file “.config” under the element as follows: YourNameSpace.AutoCompleteTitle, YourAssemblyģ. This + " : unsupported SitecoreIndexableItem type : " + scIndexable.GetType(), this) This + " : unsupported IIndexable type : " + indexable.GetType(), this) Es necesario configurar esta característica para poder utilizarla. Var scIndexable = indexable as SitecoreIndexableItem La característica de escritura avanzada permite que los usuarios puedan utilizar un desplegable de posibles elecciones como un campo de búsqueda para encontrar y seleccionar elementos en la lista de posibles elecciones. If (indexable = null) throw new ArgumentNullException("indexable") Public object ComputeFieldValue(IIndexable indexable) Your computed field should be something like: public class AutoCompleteTitle : IComputedIndexField However, I prefer to use computed fields because they are more flexible. Use a Computed field to create a copy of the title using the new data typeĪlso, you can use copy fields. Open the .config and add the following type match Ģ. Create a type in Sitecore for the auto-complete field. These are the steps to properly implement this feature:ġ. This won’t work as well because it will fail to return results such as “blue pen” where the title doesn’t start with the word “pen”. Var results = context.GetQueryable().Where(i=> i.Title.StartsWith(searchText)) Don’t use String.StartsWith() var context = index.CreateSearchContext() Please don’t ever do this, your client will come back complaining that, when their customers search for “pen” they get irrelevant suggestions such as “Dis penser”, “O pen” and “Shar pener”. Var results = context.GetQueryable().Where(i=> i.Title.Contains(searchText)) Before I go through the details, please don’t do the following: Don’t use String.Contains() var context = index.CreateSearchContext() Search responses can also be configured to include snippets (document excerpts) featuring highlighted text. Solr includes a rich set of search parameters for controlling how terms are highlighted. The NGram analyzer is used here to implement search auto-complete feature. Highlighting can make it easier to find relevant passages in long documents returned in a search. This article will show you how to display search suggestions using Sitecore 7 and Solr Search Provider. Solr is a very powerful search platform which provides many indexing and query time analyzers. If you are about to implement an auto-compelte text box for your search page, then you are in the right place.
