    <p>I'm working on a search/filter form based on Thinking Sphinx. There I'm having some difficulty querying a particular Sphinx field for some phrases connected by the OR operator.</p> <p>A little bit of background: I'm indexing a field called "keywords", which contains comma-separated keywords, some of which are phrases, while others are single terms. I want to filter for items that contain keyword A OR keyword B OR keyword C.</p> <p>My search yields the wrong result, since phrases don't seem to get taken into account:</p> <pre><code>Media::Set.search "Architecture", :conditions =&gt; {:keywords =&gt; "\"Computer Aided Design\"|Index-Browser|\"Shape Grammar\"" } </code></pre> <p>I tried every combination of enclosing the phrases in single/double quote with/without escaping that I could think of.</p> <p>I also tried to use the Sphinx extended query syntax, like for example so:</p> <pre><code>Media::Set.search 'Architecture @keywords ("Computer Aided Design" | Index-Browser | "Shape Grammar")', :match_mode =&gt; :extended </code></pre> <p>Again, I've experimented with tweaking the syntax in different ways.</p> <p>One by one, the keywords yield the following results:</p> <ul> <li>Computer Aided Design: 1 match</li> <li>Index-Browser: 1 match </li> <li>Shape Grammar: 3 matches</li> </ul> <p>I'd expect the search for the three keywords, joined by the OR operator to yield 5 matches, but I only ever get the one match for "Index-Browser", which happens to be the only single term (no spaces).</p> <p>What am I doing wrong? Or did I misunderstand how the OR operator is supposed to working?</p> <p>Thanks in advance for any pointers,</p> <p>~ Andrea </p>

    1. COHi Andrea. Sorry I've not responded sooner on the TS list, but let's work through it here... what does your define_index block look like?

    2. COHi Pat, thanks for getting back to me about this. I don't actually have a define_index block, since I'm using xmlpipe2 as a data source, but "keywords" is set up as a sphinx field and the data in that field is basically a comma separated list of keywords. Shall I create a gist about the code that creates the xml?

    3. COHmm, what would be better is a gist of the XML output for the 5 matches you're expecting. That said, I really do expect your second example to work - and the first one probably should too.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
