if (!File.Exists(fileName))
BaseDocument document = getBaseDocument(TestFilePath.InputFilePath + fileName);
document.CacheSearchInfo(TestFilePath.InputFilePath + cacheFile);

// Create search result.
SearchResult sResult = new SearchResult();

// Search and store the result in the entity of search structure.
BaseDocument.Search(TestFilePath.InputFilePath + cacheFile, option, sResult);
