                <link>https://jira.mongodb.org/browse/SERVER-35045</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Applying a unique index to a single text field has unexpected behavior with spaces.&lt;/p&gt;

&lt;p&gt;OS: Windows 10&lt;/p&gt;

&lt;p&gt;For example:&lt;/p&gt;

&lt;p&gt;Inserting &quot;test co&quot; and &quot;test2 co&quot; fail uniqueness.&lt;/p&gt;

&lt;p&gt;Inserting &quot; co&quot; and &quot;&#160; &#160; &#160; &#160;co&quot; fail uniqueness.&lt;/p&gt;

                            <comment id="1897459" author="matherz831" created="Mon, 21 May 2018 19:03:04 +0000"  >&lt;p&gt;Thanks for the help Andy. You are right, this is not a bug, but user error. I should be just be indexing strings.&lt;/p&gt;

&lt;p&gt;As far as it possibly being a bug that mongodb allows the creation of a unique text index, I do see it possibly being useful when used with weights.&lt;/p&gt;

&lt;p&gt;You may close/delete the issue.&lt;/p&gt;</comment>
                            <comment id="1894808" author="schwerin" created="Fri, 18 May 2018 00:31:31 +0000"  >&lt;p&gt;It may be a bug that we allow you to create a unique text index. A text index splits strings into tokens (words), and those tokens form the keys. So in your example, &quot;co&quot; is a duplicates key.&lt;/p&gt;

&lt;p&gt;Are you trying to build a text index, or just index strings? If the latter, you need to change your index spec.&lt;/p&gt;</comment>
