Ignore stopwords in examine index search

Questions

We want to search for “OR-SA 1121” but the problem is that “OR” is indexed a sa Stopword. How can we fix this Problem?
This is our code:

```
`private IEnumerable DoIndexSearch(string query, string category, int page, int pageSize, IIndex index,
out long totalResults)
{
var currentCulture = CurrentPage.GetCultureFromDomains().ToLower();

var fields = new string[] { "articleNumber", "nodeName", "articleLead", "content", "lead" };

var operation = index.Searcher
    .CreateQuery(IndexTypes.Content).GroupedNot(new string[] { "meta_dontIndexSearch" }, "1")
    .And()
    .GroupedNot(new[] { "templateID" }, "0")
    .And()
    .GroupedAnd(new string[] { "path" }, ("-1," + this.GetRootNode().Id).MultipleCharacterWildcard());

if (category == "other")
{
    operation = operation.And().GroupedNot(new string[] { "__NodeTypeAlias" }, new string[] { "product", "story", "productTech" });
}
else if (!string.IsNullOrEmpty(category))
{
    if (category == "product")
    {
        operation = operation.And().GroupedOr(new string[] { "__NodeTypeAlias" }, new string[] { "product", "productTech" });
    }
    else
    {
        operation = operation.And().GroupedOr(new string[] { "__NodeTypeAlias" }, category);
    }
}

if (!string.IsNullOrEmpty(query))
{
    char[] separators = { ' ', '/', '-' };
    var searchWordList = query.Split(separators);
    searchWordList = searchWordList.Where(x => x != "").ToArray();
    searchWordList = searchWordList.Where(x => !string.IsNullOrEmpty(x)).ToArray();
    operation = searchWordList.Aggregate(operation, (current, searchWord) => current.And()
        .GroupedOr(fields,
            (!string.IsNullOrEmpty(searchWord) ?  searchWord + "*" : searchWord).MultipleCharacterWildcard()));
}

var results = operation.OrderByDescending(new SortableField("articleNumber", SortType.String))
    .Execute();

if (results == null) return DefaultSearchResult(out totalResults);

totalResults = results.TotalItemCount;


var searchResults = GetResultsAsPublishedContents(results);

var firstPart = searchResults.Where(x =>
    x.HasValue("articleNumber") && x.Value<string>("articleNumber")[0].ToString() == query).OrderByDescending(x => x.Value<string>("articleNumber"));

var secondPart = searchResults.Where(x =>
    x.HasValue("articleNumber") && x.Value<string>("articleNumber")[1].ToString() == query);

var specialList = firstPart.Concat(secondPart);

var lastPart = searchResults.Where(x =>
    (x.HasValue("articleNumber") && x.Value<string>("articleNumber")[0].ToString() != query) || !x.HasProperty("articleNumber"));

var newOrderedList = specialList.Concat(lastPart);
var pagedList = GetPagedResults(page, pageSize, newOrderedList);

return pagedList;

} \``

You are able to remove/add stop words by creating your own analyzer. There is some more information in this thread:

thanks for your response patrick.
This approach doesnt seem to work since the StandardAnalyzer class cant be inherited from. seems like this was an approach in an older version of umbraco.

Or did anyone implement something similar with the StandardAnalyzer in Umbraco 13?
