If you need to return documents that contain the exact phrase clear and present danger, you must:. Returns documents that contain both the word clear and the phrase present danger. All these words are noise words and you must remove these words from the list to make dtSearch index these files Note: Connector words such as and and not are also included by default in the noise word list. Please take a look at the following examples: You must use double quotes when searching for exact phrases that contain words that are reserved as dtSearch operators, such as the Boolean connectors AND, OR. Returns the exact phrase: apple grape bananaĭoes not return partial phrase: apple grapeĭoes not return standalone word: grape banana Does not return standalone word: orange. You only need to use double quotes when searching for a word that is a dtSearch operator (see the next section). There is no rule that requires double quotes around a phrase of any number of words. For example, if you search for apple pear, dtSearch returns documents that contain the exact phrase apple pear. Searching for words right next to each other with no operator between them constitutes an exact phrase in dtSearch. Watch the following Special Considerations for dtSearch video. For example, if your exact phrase search is an acronym like ACT, you must build a case-sensitive dtSearch index. All characters in a dtSearch index are normalized to lowercase. dtSearch indexes are case insensitive by default. For more information, see Searching for symbols. In order to search for these symbols, you must index the character by modifying the alphabet file. The colon (:) and ampersand (&) are not used by Relativity but are still considered a syntax term by the dtSearch index. Verify that a given character is defined as causing a word break before using it as a space in a dtSearch. The underscore (_) is not recognized as a space by default. Special characters or operatorsĪuto-recognition of dates, emails, credit cardsįor the list of the special characters recognized as spaces that cause word breaks, see Noise words and the alphabet file. The following table summarizes the syntax options available for queries run against a dtSearch index. Write from the source to the destination.DtSearch includes special characters and other operators that you can use to define search criteria.

return every document in the specified range (using xfirstword) Sf.SelectItems(indexId, lastDbDocId + 1, int.Parse(latestIndexDocId.ToString()), true) only select new records (from one greater than the last DocId in the DB to the last DocId in the index itself Uint latestIndexDocId = indexInfo.LastDocId ĭ sf = new SearchFilter() Int lastDbDocId = db.IndexDocuments.OrderByDescending(i => i.DocId).FirstOrDefault().DocId

MyDataBase db = new MyDataBase() //again, custom code not included - link to EntityFramework entity Ij.IndexingFlags = IndexingFlags.dtsIndexKeepExistingDocIds ĭataTable newIndexDoc = MakeTempIndexDocTable() //this is a custom method not included in this example just creates a DataTable with the appropriate columns make sure the updated index doesn't change DocIds For that, I used the following code: string indexPath = (IndexJob ij = new ())
#Dtsearch file list update
I did indeed have to set the dtsKeepExistingDocIds flag in my index update routine.įrom there, I only wanted to add the newly created DocIds to my SQL database. So, I used part of user2172986's response, but combined it with some additional code to get the solution to my question. Ij.IndexPath = indexInfo = jobDone = ij.Execute() But just in case it helps: MyDatabaseContext db = new StateScapeEntities()
#Dtsearch file list how to
This, however, takes FOREVER, and doesn't address the issue of how to simply append new records as they are added to the index. I have code to simply return all the records in the index and add them one by one to the DB. From there, I will add a column with my foreign key to allow me to combine text and database searches. I am using dtSearch on combination with a SQL database and would like to maintain a table that includes all DocIds and their related FileNames.
