The following four documents available for search
1. ESP_Query_Integration_Guide.pdf
2. ESP_Query_Language_Parameters_Guide.pdf
3. ESP_SFE_Dev_Guide.pdf
4. README-1.0.17.html
After indexing, there were 2 navigators seen - Size and Formats.

In the Formats navigator we got 2 modifier Adobe PDF and Text, we want to exclude the modifier 'Adobe Pdf' expecting a result count of 1.

Any code snippet for implementing the above scenario through Java Search API.

Thanks in Advance
