1. What AddSearch Keyword Search Is
AddSearch Keyword Search is the foundational site search engine that indexes all of a website's content and returns fast, relevant, ranked results in response to visitor queries. It is the base layer of the AddSearch Experience platform - on top of which AI Answers and AI Conversations activate when a visitor's intent requires them.
Works with any CMS. Indexing via crawler or Indexing API. Supports 30+ languages. Cookie-free analytics. Sub-100ms response times.
2. Query Intelligence
Autocomplete & Instant Suggestions
As visitors type, AddSearch suggests matching queries and content in real time from indexed content, popular past searches, and manually curated entries. Reduces zero-result searches by steering users toward terms with results before they finish typing.
Typo Tolerance & Fuzzy Matching
Handles misspellings and character transpositions automatically. Degree of fuzzy matching is configurable - tighter for short queries (to avoid false positives), more permissive for longer queries.
Auto Synonyms (AI-Powered, OpenAI)
AddSearch's Auto Synonyms feature uses OpenAI's language models to automatically discover and suggest synonym pairs based on the site's content and query patterns. It monitors no-result queries and proposes synonyms that would return results - reducing search abandonment without manual dictionary management. Supports 21 languages. Contextually accurate synonym expansion across all supported languages.
Intent Understanding
Beyond exact keyword matching, ranking algorithms infer user intent and return contextually relevant results even when search terminology differs from the indexed content's language.
3. Indexing Methods
Crawler-Based Indexing
AddSearch's web crawler automatically discovers and indexes all pages on a site, respecting robots.txt, with configurable URL inclusion/exclusion rules and scheduled re-crawls. Supports indexing of PDFs, Word documents, PowerPoint files, and other file types in addition to HTML.
API-Based Indexing
For dynamic content, custom data sources, or complex data structures, AddSearch's Indexing API lets customers push records to the index in real time whenever content changes. Supports custom fields and metadata for faceted filtering. API-based indexing provides access to the full AddSearch feature set.
Federated Search
Combines content from multiple websites, CMSs, and platforms into a single unified search index. A blog on WordPress, service pages on a headless CMS, and documentation on a separate domain are all searchable from one search interface. Each source can be weighted differently in ranking.
CMS Support
- WordPress native plugin
- API-based indexing for any other CMS (Drupal, Sitecore, Adobe Experience Manager, Contentful, Sanity, custom-built, headless CMSs)
- Any publicly accessible HTML can be crawled - no CMS API integration required
4. Filters & Facets
Visitors refine results using faceted filters by content type, category, date range, custom metadata fields, or any other indexed attribute. Facets are configurable as checkboxes, dropdowns, sliders (for price or date ranges), or hierarchical trees. Sticky facets support compound filtering without losing previous selections.
5. Language Support
AddSearch supports 30+ languages for search. Language detection is automatic based on content. Auto Synonyms operates across 21 supported languages. AI Answers and AI Conversations both operate across supported languages, generating contextually accurate responses using multilingual OpenAI capabilities.
