ExamineX for Elasticsearch does not parse Lucene query correctly

[raimondkempees-arc]

Describe the bug I'm trying out ExamineX for Elasticsearch and find that the query posted to Elasticsearch is incorrect in the following cases:

Note I'm probably doing something stupid.

When I do this:

           if (_examineManager.TryGetIndex(Constants.UmbracoIndexes.ExternalIndexName, out var examineIndex))
        {
            var searcher = examineIndex.Searcher;
            var query = searcher.CreateQuery().Field("content", q);

            var results = query.Execute().Select(r => r.AllValues);

            _logger.LogDebug("We have {x} results.", results.Count());
        }

The output is: "type" : "parse_exception", "reason" : "request body is required", "stack_trace" : "org.elasticsearch.ElasticsearchParseException: request body is required\n\tat org.elasticsearch.server@8.6.1/

When I do this:

 if (_examineManager.TryGetIndex(Constants.UmbracoIndexes.ExternalIndexName, out var examineIndex))
        {
            var searcher = examineIndex.Searcher;
            var query = searcher.CreateQuery("content", BooleanOperation.And).Field("content", q);

            var results = query.Execute().Select(r => r.AllValues);

            _logger.LogDebug("We have {x} results.", results.Count());
        }

I get

"stack_trace" : "org.apache.lucene.queryparser.classic.ParseException: Cannot parse '+x__IndexType:content +':

When I do a plain

searcher.Search("test")

I get back one result.

To Reproduce See above.

Expected behavior I expect to get search results back.

Versions

• ExamineX.Shared version 6.0.8

Hi @raimondkempees-arc,

A few questions:

• In the above examples, what is the value of q?
• What version/service of Elastic Search are you using?

When testing locally against the elastic 8.12.1 container using the following code, I get the following results:

using (Setup.Index.ProcessNonAsync())
{
    Setup.Index.IndexItems(new[] {
        ValueSet.FromObject(NewId(), "content",
            new { content = "test" }),
        ValueSet.FromObject(NewId(), "content",
            new { content = "asdf" }),
    });
}

var searcher = GetDelayedSearcher();
var query = searcher.CreateQuery("content", BooleanOperation.And).Field("content", "test");

var result = query.Execute();
var results = result.Select(r => r.AllValues);

Console.WriteLine("We have {0} results.", result.TotalItemCount);
Console.WriteLine("We have {0} values.", results.Count());

results:

  Standard Output:
