How Full-Text Search Works

The search engine scans all newspaper content including:

• Titles: Issue headlines and descriptions (weighted highest)
• Descriptions: User-added descriptions (weighted high)
• OCR Text: All extracted text from newspaper pages (weighted normal)

Result Ranking Explained

Results are sorted by relevance score based on:

• Title matches rank highest (10x weight)
• Description matches rank high (5x weight)
• OCR text matches rank normal (1x weight)
• Multiple keyword matches score higher than single matches
• Exact phrase matches score higher than separate word matches

Single vs Multiple Keywords

Phrase Searches with Quotes

Use quotes to search for exact phrases:

Broad to Narrow Strategy

Start broad, then add terms to narrow results:

1. Start with general term: mayor
2. Add specific term: mayor election
3. Add date filter: mayor election + filter to 1920s
4. Add publication filter if needed

Synonyms and Variations

Try different words for the same concept:

• People: Try full names, last names only, nicknames
• Places: Try "city of X" and just "X", old vs current names
• Events: Try formal and informal names
• Concepts: Try multiple related terms (automobile, car, vehicle)

Publication Filter Deep Dive

Limit results to specific newspapers:

• "All Publications" - Searches entire archive
• Single publication - Focuses on one newspaper
• When to use: Looking for coverage of local events, comparing perspectives
• Pro tip: Each publication has unique topics - browse before searching

Date Range Strategies

Use date filters to focus searches:

Combining Multiple Filters

Use publication + date filters together for precision:

• Example: "flood" + "Springfield Gazette" + 1920-1925
• Finds flood coverage in specific newspaper during specific period
• More filters = fewer but more relevant results

When to Use vs Not Use Filters

Common OCR Errors to Expect

OCR isn't perfect. Historical newspapers often have these recognition errors:

Trying Alternate Spellings

If you're not finding expected results, try:

• Search for partial words if full word not found
• Try common OCR substitutions (see table above)
• Use simpler search terms (avoid complex names)
• Search for related terms that might appear nearby

Searching Partial Words

Sometimes searching part of a word helps:

• If "Massachusetts" not found, try "Massachu" or "chusetts"
• Useful when OCR may have split or merged words
• Works for unusual names or long words

Punctuation and Special Characters

• Search ignores most punctuation
• Hyphens, apostrophes may or may not be recognized
• Try with and without: don't vs dont
• Dollar signs, percentages usually not searchable

Using Suggested Topics

• Suggestions are based on frequently mentioned phrases
• Click any suggestion to search immediately
• Helps discover what topics are covered in archives
• Useful when you're not sure exact wording used

Popular Phrases by Publication

Search Tips by Research Type

"No Results Found" - What to Try

1. Remove filters - Make search broader
2. Try fewer keywords - Start with one or two words

4. Use partial words - Search root of word
5. Try synonyms - Different words for same concept
6. Expand date range - May have occurred different year
7. Search all publications - Remove publication filter

Too Many Results - Narrowing Strategies

1. Add more keywords - Make search more specific
