How to filter solr suggestions only from particular path

Question

I recently tried solr autosuggest search in my local,

Steps I followed :

1. Added configuration in master in sensoft_master_index\conf\solrconfig.xml

2. Restarted solr8.1 service in services

3. in C# code,

public IEnumerable GetSuggestion(string term) {

        try
        {
            using (var context = ContentSearchManager.GetIndex("sitecore_master_index").CreateSearchContext())
            {
                SolrSuggestQuery query = term;
                var options = new SuggestHandlerQueryOptions
                {
                    Parameters = new SuggestParameters
                    {
                        Count = 3
                    }
                };

                var result = context.Suggest(query, options);

                return result.Suggestions["default"].Suggestions.Select(a => a.Term);
            }
        }
        catch (Exception e)
        {
            System.IO.File.WriteAllText(@"D:\test1.txt", e.ToString());
        }
        return rr;
    }

I'm getting the results But now I want to filter the suggestion only from a particular path: for ex: I need the suggestions that have the path: /sitecore/content/home

what configuration changes I need to make? Any help

Answer 1

To filter suggestion result only particular path, there is three possible solutions:

Option 1: Set contextField as _fullpath and pass path in ContextFilterQuery

 <str name="contextField">_fullpath</str>

using (var context = ContentSearchManager.GetIndex("sitecore_master_index").CreateSearchContext())
            {
                SolrSuggestQuery query = term;
                var options = new SuggestHandlerQueryOptions
                {
                    Parameters = new SuggestParameters
                    {
                        Count = 3,
                        Build = true,
                        ContextFilterQuery="SomePath"
                    }
                };
                var result = context.Suggest(query, options);
                return result.Suggestions["default"].Suggestions.Select(a => a.Term);
            }

Option 2: Filter results on basis of template

<str name="contextField">_template</str>

using (var context = ContentSearchManager.GetIndex("sitecore_master_index").CreateSearchContext())
            {
                SolrSuggestQuery query = term;
                var options = new SuggestHandlerQueryOptions
                {
                    Parameters = new SuggestParameters
                    {
                        Count = 3,
                        Build = true,
                        ContextFilterQuery="sometemplateId"
                    }
                };
                var result = context.Suggest(query, options);
                return result.Suggestions["default"].Suggestions.Select(a => a.Term);
            }

Option 3 Create a computed field where you can pass true and false based on the path and set the computed field name in contextField

<str name="contextField">computedfieldname</str>

using (var context = ContentSearchManager.GetIndex("sitecore_master_index").CreateSearchContext())
            {
                SolrSuggestQuery query = term;
                var options = new SuggestHandlerQueryOptions
                {
                    Parameters = new SuggestParameters
                    {
                        Count = 3,
                        Build = true,
                        ContextFilterQuery="true"
                    }
                };
                var result = context.Suggest(query, options);
                return result.Suggestions["default"].Suggestions.Select(a => a.Term);
            }

You need to add to the

<str name="contextField">_template</str> 

This will allow you filter our search results based on path , more filtering can be applied by using a custom Index which is mapped to a particular location

I don't see any direct functionality for the same as far as I know. But I can suggestion one work around.

Create a custom index field. Fill it's value only for the desired teamplate and path. Use the same custom index field for below configuration:

<str name="field">PUT_YOUR_CUSTOM_FIELD_NAME_VISIBLE_IN_SOLR</str>

This would definitely solve your problem.
