Real-World Use Cases

• •A mid-size fashion retailer implementing typo-tolerant, synonym-aware product search in under a week using Algolia's React InstantSearch components and merchandising dashboard
• •A marketplace with 2M SKUs using Algolia's A/B testing to optimize search result ranking rules, increasing search-to-purchase conversion by 18%

const client = algoliasearch("APP_ID", "SEARCH_KEY");

const search = instantsearch({
  indexName: "products",
  searchClient: client,
});

search.addWidgets([
  searchBox({ container: "#search-box" }),
  hits({
    container: "#hits",
    templates: {
      item: (hit) =>
        '<div>${hit.name} - ${hit.price}</div>',
    },
  }),
]);
search.start();

Real-World Use Cases

• •A large marketplace running Elasticsearch with custom BM25 + kNN hybrid scoring, A/B testing relevance models across 50M product listings with full control over ranking algorithms
• •An electronics retailer using OpenSearch with custom analyzers for technical product specifications, enabling searches like '16GB DDR5 laptop under $1000' with precise attribute matching
• •A B2B distributor with complex product hierarchies using Elasticsearch's nested queries to match searches against multi-level category trees with attribute inheritance

Integration Example

from elasticsearch import Elasticsearch

es = Elasticsearch("https://my-cluster:9200")

# Hybrid search: BM25 + kNN vector
results = es.search(
    index="products",
    body={
        "query": {
            "bool": {
                "should": [
                    {"match": {"name": "blue running shoes"}},
                    {"knn": {
                        "field": "embedding",
                        "query_vector": query_embedding,
                        "k": 20,
                        "num_candidates": 100
                    }}
                ]
            }
        },
        "size": 20
    }
)

for hit in results["hits"]["hits"]:
    print(f"{hit['_source']['name']} ({hit['_score']:.2f})")

Real-World Use Cases

• •A fashion brand using Constructor's ML-optimized ranking to automatically promote high-margin items that match shopper intent, increasing revenue per search by 22%

  apiToken: "YOUR_API_TOKEN",
});

// Search with personalization
const results = await cio.search.getSearchResults("running shoes", {
  filters: { brand: ["Nike", "Adidas"] },
  sortBy: "relevance",
  userId: "user-123",  // enables personalization
  page: 1,
  resultsPerPage: 20,
});

results.response.results.forEach((item) => {
  console.log('${item.data.name} - ${item.data.price}');
});

Real-World Use Cases

const resp = await fetch(
  "https://core.dxpapi.com/api/v1/core/?account_id=ACCOUNT" +
  "&domain_key=YOUR_DOMAIN" +
  "&request_type=search" +
  "&q=summer+dresses" +
  "&fl=pid,title,price,thumb_image" +
  "&rows=20" +
  "&user_id=visitor-abc",
  { headers: { "Authorization": "Bearer YOUR_TOKEN" } }
);

const data = await resp.json();
data.response.docs.forEach((product) => {
  console.log('${product.title} - ${product.price}');
});

Real-World Use Cases

Integration Example

import Typesense from "typesense";

const client = new Typesense.Client({
  nodes: [{ host: "localhost", port: 8108, protocol: "http" }],
  apiKey: "YOUR_KEY",
});

// Search with typo tolerance and facets
const results = await client
  .collections("products")
  .documents()
  .search({
    q: "runnng shoes",  // typo handled automatically
    query_by: "name,description,brand",
    filter_by: "price:<100 && in_stock:true",
    facet_by: "brand,color,size",
    sort_by: "popularity:desc",

Integration Example

<!-- Nosto integration for Shopify -->
<script src="https://connect.nosto.com/include/YOUR_ACCOUNT"
        async></script>

<!-- Search placement -->
<div class="nosto_element" id="nosto-search"></div>

<script>
  // Programmatic search with Nosto API
  nostojs(api => {
    api.search({
      query: "summer dress",
      products: { fields: ["name", "price", "imageUrl"] },
      sessionParams: api.defaultSession(),
    }).then(result => {
      result.products.hits.forEach(product => {
        console.log(product.name, product.price);
      });
    });
  });
</script>

Real-World Use Cases

• •A B2B industrial distributor with 10M SKUs using Coveo's ML ranking to surface relevant products from a deep catalog where traditional keyword search fails on technical part numbers
• •A global retailer unifying product search across web, mobile app, and in-store kiosks with consistent AI-driven relevance and personalization across all channels
• •An enterprise marketplace using Coveo's behavioral analytics to identify search gaps (queries with no results or low click-through) and automatically suggest catalog improvements

Integration Example

// Coveo Headless search integration
import { buildSearchEngine, buildSearchBox,
  buildResultList } from "@coveo/headless";

const engine = buildSearchEngine({
  configuration: {
    organizationId: "YOUR_ORG",
    accessToken: "YOUR_TOKEN",
    search: { pipeline: "ecommerce" },
  },
});

const searchBox = buildSearchBox(engine);
const resultList = buildResultList(engine);

searchBox.updateText("industrial valve");
searchBox.submit();

// Results are ML-ranked based on user behavior signals
resultList.subscribe(() => {
  resultList.state.results.forEach((r) => {
    console.log(r.title, r.raw.ec_price);
  });
});

Real-World Use Cases

• •An indie ecommerce store replacing a slow database LIKE query with Meilisearch, getting instant typo-tolerant search across 50K products with a single Docker container
• •A marketplace startup building a search MVP in a day using Meilisearch's simple API, adding faceted filtering by category and price range without any search expertise
• •A catalog-heavy B2B site using Meilisearch's hybrid search to combine keyword matching on part numbers with semantic search on product descriptions for better discovery

Integration Example

import { MeiliSearch } from "meilisearch";

const client = new MeiliSearch({
  host: "http://localhost:7700",
  apiKey: "YOUR_KEY",
});

// Index products
await client.index("products").addDocuments(products);

// Configure searchable and filterable attributes
await client.index("products").updateSettings({
  searchableAttributes: ["name", "description", "brand"],
  filterableAttributes: ["price", "category", "in_stock"],
  sortableAttributes: ["price", "rating"],
});

// Search with typo tolerance, filters, and facets
const results = await client.index("products").search(
  "runnig shoes",  // typo handled
  { filter: "price < 150 AND in_stock = true",
    facets: ["brand", "color"] }
);
