Making the dtSearch noise word list searchable
Relativity ignores words that do not act as meaningful criteria when you create dtSearch and keyword queries. Ignored words are known as noise or noise words. Search indexes automatically include the default list of noise words. However, you can edit this list in the dtSearch list to suit your needs. This article includes an overview of noise words and steps to create custom lists.
Default noise word list
Relativity references the default list of noise words each time you create a new index. System admins cannot edit noise words in keyword searches. The default noise word list consists of punctuation marks, single letters and numbers, and the following words:
| Begins with | Noise words |
|---|---|
| A | a, about, after, all, also, an, and, another, any, are, as, at |
| B | be, because, been, before, being, between, both, but, by |
| C | came, can, come, could |
| D | did, do |
| E | each, even |
| F | for, from, further, furthermore |
| G | get, got |
| H | had, has, have, he, her, here, hi, him, himself, his, how, however |
| I | i, if, in, indeed, into, is, it, its |
| J | just |
| L | like |
| M | made, many, me, might, more, moreover, most, much, must, my |
| N | never, not, now |
| O | of, on, only, or, other, our, out, over |
| S | said, same, see, she, should, since, some, still, such |
| T | take, than, that, the, their, them, then, there, therefore, these, they, this, those, through, thus, to, too |
| U | under, up |
| V | very |
| W | was, way, we, well, were, what, when, where, which, while, who, will, with, would |
| Y | you, your |
Note: Relativity ignores noise words. However, Relativity does not ignore their position in the search phrase set. So, if you execute the query apple w/6 pear, the search returns the phrase apple tree is far from the pear even though it contains the noise words is, from and the.
dtSearches and noise words
The default list of noise words is the same in a dtSearch as in a keyword search. The primary difference is that you can customize the dtSearch index list. For example, if the word never is important to your litigation, remove it from the noise words list, so that your search results always return that word.
To create a custom noise word list, perform the following:
- Create a new dtSearch index, and then name it dtSearch - updated noise words.
- Select your extracted text search for the Searchable set.
- Delete the word never from the Noise Words list.
- Save the list, and then perform a full build on your new index.
Noise words in languages other than English
You can set up noise words to search documents in other languages. If the workspace primarily contains of documents in a different language, see this page for an overview of suggested noise words for use in nineteen additional languages.
