TypeError C is not a function

[pdhoward]

Thanks much for the response ... I corrected the method as you noted above it worked beautifully!
.add(doc); // pass in the object since I used the doc descriptor

Very excited about this search capability!

Hello sorry for the late answer. I do not fully understand your intend, but I can provide you a running version:

const FlexSearch = require("flexsearch");

// provide a document descriptor for each index
// the field "id" and at least one "field" is mandatory.

const settings = {
    "bookstore": {
        preset: "score",
        doc: {
            id: "id",
            field: ["intent", "text"]
        }
    },
    "pizzashop": {
        encode: "extra",
        tokenize: "strict",
        depth: 5,
        threshold: 5,
        doc: {
            id: "id",
            field: ["intent", "text"]
        }
    },
    "votingbooth": {
        encode: "advanced",
        tokenize: "forward",
        threshold: 5,
        doc: {
            id: "id",
            field: ["intent", "text"]
        }
    }
};

const index = {};

const add = (cat, doc) => {
    (index[cat] || (
        index[cat] = new FlexSearch(settings[cat])
    )).add(doc);
};

const search = (cat, query) => {
    return index[cat] ? index[cat].search(query) : [];
};

// provide documents which have the same structure as defined in the document descriptor above

const bookstore = [{
    id: 0,
    intent: "intent",
    text: "text"
},{
    id: 1,
    intent: "intent",
    text: "i am searching for a book"
}];

const pizzashop = [{
    id: 0,
    intent: "intent",
    text: "text"
},{
    id: 1,
    intent: "intent",
    text: "howdy"
}];

const votingbooth = [{
    id: 0,
    intent: "intent",
    text: "text"
},{
    id: 1,
    intent: "intent",
    text: "i need directions"
}];

// add a full document or an array of documents to the index

add("bookstore", bookstore);
add("pizzashop", pizzashop);
add("votingbooth", votingbooth);

// search

var result1 = search("bookstore", "i am searching for a book"); // --> [1]
var result2 = search("pizzashop", "howdy"); // --> [1]
var result3 = search("votingbooth", "i need directions"); // --> [1]

console.log(`========== FAST SEARCH TEST ==========`);
console.log(result1);
console.log(result2);
console.log(result3);

I hope it helps you.

You can also skip the doc descriptor and just pass one string value with index[cat].add(id, string), but this will return just ids as a result. If that fits your needs then this is noticeably faster.

One last thing :) the next version will provide you a "where" field in the custom search, this will replace the by-hand-category-splitting completely
