Keyword search is not working with keyword containing space using SOLR

Question

Sitecore 9.3

I have a keyword search implemented and working fine until I use spaces in the keyword. As soon as I include space in a keyword it doesn't show me any results. Here is my query.

var keywordQuery = PredicateBuilder.True<SearchResultItem>();
keywordQuery = keywordQuery.Or(item => item.ShortTitle.Contains(keyword));
keywordQuery = keywordQuery.Or(item => item.LongTitle.Contains(keyword));

I have also gone through this article https://chrisperks.co/2018/02/12/sitecore-9-contentsearch-solr-query-quirks-with-spaces-and-wildcards/, discussed the same problem, and suggests to use "StartsWith" instead of "Contains" but it didn't help.

Answer 1

This depends on a couple of factors like:

1. Your ShortTitle and LongTitle fields configuration, what analyzer you used to index these fields.
2. What is your target, do you want to match the whole keyword (with spaces), do you want to match single words? do you want to match all single words or any?

This is very useful link to understand the analyzers available: https://community.sitecore.net/technical_blogs/b/getting_to_know_sitecore/posts/understanding-analyzers-and-sitecore-7

Also, here is a trick I use for searching keyword that contain spaces:

var keywordSplitted = KeyWord.Split(' ');
var predicate = PredicateBuilder.True<CustomSearchResultItem>();

foreach (var word in keywordSplitted)
{
    predicate = predicate.And(item => item.LongTitle.Contains(word));
}
