Finding Articles

OJS includes a built-in full-text search engine that indexes article titles, abstracts, authors, keywords, and — where enabled — the full body of published articles. You can also discover OJS-hosted content via Google Scholar and other external databases.

The Search Bar

A search bar appears in the top navigation area of most OJS themes.

Click the Search icon or field
Type one or more keywords
Press Enter or click Search

Results are ranked by relevance and show the article title, authors, journal section, and a brief excerpt.

Basic Keyword Search

Query	What It Matches
`climate change`	Articles containing both words anywhere in indexed fields
`"climate change"`	Exact phrase in that exact word order
`climate -ocean`	Articles about climate but not mentioning ocean
`author:Smith`	Articles where an author's name includes Smith

Phrase search

Wrap phrases in double quotation marks to find exact matches. "open peer review" returns only articles containing that exact phrase, filtering out unrelated results.

Advanced Search

Click Advanced Search (below the search bar or at the bottom of search results) to access field-specific filters:

Field	Description
All	Searches all indexed fields simultaneously
Author	Searches author names only
Title	Searches article titles only
Abstract	Searches abstract text only
Full Text	Searches the body of articles (if full-text indexing is enabled)
Supplementary Files	Searches supplementary file metadata
Date Range	Filter results by publication date (from / to)
Journal	Restrict results to a specific journal (multi-journal installations)

Using Advanced Search

Navigate to the search page (click Search in the header, then Advanced Search)
Enter your query in one or more field-specific boxes
Set a Date Range if you want results from a particular period
Click Search

Search Tips and Boolean Operators

OJS search supports basic Boolean logic:

Operator	Example	Effect
`AND` (default)	`vaccine AND efficacy`	Both terms must appear
`OR`	`vaccine OR vaccination`	Either term may appear
`NOT` / `-`	`malaria -falciparum`	Excludes the second term
`"..."`	`"systematic review"`	Exact phrase match
`*` (wildcard)	`pharmac*`	Matches pharmacy, pharmacology, pharmaceutical, etc.

Case sensitivity

OJS search is case-insensitive. DNA, dna, and Dna return the same results.

Narrow broad queries

If a basic keyword search returns too many results, switch to Advanced Search and enter your term in the Title or Abstract field alone. This significantly reduces noise.

Browsing by Keyword

Every article can be tagged with author-supplied keywords. To browse by keyword:

Click any keyword tag on an article's landing page
OJS returns all articles across all issues that share that keyword
Combine with date-range filters to find recent work

Searching Across Journals

On multi-journal OJS installations, a site-level search spans all hosted journals:

Navigate to the main site homepage (e.g., https://journals.example.edu/)
Use the search bar there — results come from all journals on the platform
Use the Journal filter in Advanced Search to restrict to a single title

note

Single-journal installations only search within that journal. For cross-publisher discovery use Google Scholar or a subject database.
