How It Works

Lumenare Search creates a custom database table to store keyword indexes for fast searching. When content is published or updated, keywords are extracted from:
* Post titles (weight: 3 – highest relevance)
* Post excerpts (weight: 2 – medium relevance)
* Post content (weight: 1 – base relevance)

The plugin automatically indexes your content and keeps the index up-to-date as you publish or update posts. Search queries are processed through the custom index for fast, relevant results.

Keyword Match Modes

Match ANY (OR) – Default
* Returns results containing at least one of the search keywords
* Best for: Broad topic searches, exploratory queries, maximizing results
* Example: “Sega Master System” finds posts with “Sega” OR “Master” OR “System”

Match ALL (AND) – Precision
* Returns only results containing ALL search keywords
* Best for: Product names, specific phrases, technical queries
* Example: “Sega Master System” finds only posts with “Sega” AND “Master” AND “System”

Advanced Features

• Stop Words: Configure which common words to exclude from indexing (e.g., “a”, “an”, “the”)
• Synonyms: Define groups of equivalent words (e.g., “car, automobile, vehicle”)
• Fuzzy Matching: Typo-tolerant search with configurable threshold (1-5 character differences)
• Phrase Boosting: Define important phrases that receive relevance boosts when searched
• Security Filtering: Automatic filtering of dangerous characters and patterns
• Security Logging: Track filtered queries for security monitoring
