firebase Filters and pagination <p>I'm trying to make a searchable list of posts saves at firebase so i have my firebse db like this</p> <pre><code>{ "post": { "postId": { "title": "bla bla bla", "date": "1/1/2015" }, "postId2": { "title": "bla bla bla", "date": "2/1/2015" } }} </code></pre> <p>Now I want to filter by title, only post that their title starts with "bla bla" and then do paging and sort by date so I made this code:</p> <pre><code> var posts=new Firebase(URL + "/post"); posts=posts.orderByChild("title").startAt("bla bla").endAt("bla bla"+"z");//this will only show posts that starts with bla bla posts=posts.orderByChild("date").startAt(10).limitToFirst(10);//this will filter and show only the second page posts.on("value", function (raw_data) { //showing the results and more }); </code></pre> <p>each of the queries works but when i put them together i get an error</p> <blockquote> <p>Query.orderByChild: You can't combine multiple orderBy calls.</p> </blockquote> <p>How can I do it? I prefer not too use my own server and copy the data to my server and do it there</p>
