MongoDB Text Search AND multiple search words

Question

I have an index on an array \"keys\" that I am using to provide full text functionality to my applicaiton.

With the release of 2.4.3, I\'d like to utilize the \"text

Answer 1

As @alecxe pointed out earlier, to do AND search on text index column you need to double quote each search word. Below is a quick one-liner for your requirement.

db.supplies.runCommand("text", {search: "printer ink".split(" ").map(str => "\""+str+"\"").join(' ')})

Answer 2

You can wrap each word in double-quotes:

let keywords = ctx.params.query.split(/\s+/).map(kw => `"${kw}"`).join(' ');
match.$text = { $search: keywords, $caseSensitive: false };

There is a downside if the user inputs a quoted string this will not work. You'd have to parse out quoted strings first.

Here is a simple function I made to search using subwords in node. Hope it helps someone

Let's suppose a user search for pri nks so it should satisfy printer and inks but $text search doesn't allow for this so here is my simple function:

    var makeTextFilter = (text) => {
    var wordSplited = text.split(/\s+/);
    /** Regex generation for words */
    var regToMatch = new RegExp(wordSplited.join("|"), 'gi');
    let filter = [];
    searchFieldArray.map((item,i) => {
        filter.push({}); 
        filter[i][item] = {
            $regex: regToMatch,
            $options: 'i'
        }
    })

    return filter;
  }

and use it in your query like this

let query = {...query, $or: makeTextFilter(textInputFromUser)}
tableName.find(query, function (err, cargo_list)

Answer 4

Give a try to:

db.supplies.runCommand("text", {search:"\"printer\" \"ink\""})

Also, here's a quote from docs:

If the search string includes phrases, the search performs an AND with any other terms in the search string; e.g. search for "\"twinkle twinkle\" little star" searches for "twinkle twinkle" and ("little" or "star").

Hope that helps.
