AnalyzerDef and search queries

[ahsanbagwan]

When I test this on the test server for queries like filter=displayName=="john" (not complete endpoint)
I receive empty response like so,
{"data":[]} whereas I was expecting the response to be populated accordingly with search results.

What am I doing wrong in the below AnalyzerDef?

@AnalyzerDef(name = "case_insensitive",
  tokenizer = @TokenizerDef(factory = NGramTokenizerFactory.class, params = {
    @Parameter(name = "minGramSize", value = "3"),
    @Parameter(name = "maxGramSize", value = "10")
  }),
  filters = {
    @TokenFilterDef(factory = LowerCaseFilterFactory.class)
  }
)
