Sometimes a reader remembers a detail from a document but not its title. A search for that word is useful only if the library can find it where it is actually written.
DocToucan Pro adds indexed file-content search to the Document library. In this example, guyline appears inside a TXT setup-notes file, but not in that Document’s title or description. The search returns the reference and a matching passage, helping the reader decide whether to open it.

Try the same search
Open the file-search tour in the Cairn & Fern demo. It uses fictional outdoor-equipment resources, so you can explore the workflow without supplying your own files or signing in.
Enter guyline in Search documents, then choose Update results. The results include the Ridgeway 2 setup notes alongside the pitching guide. Look at the TXT result: the highlighted word appears in a passage from the indexed file contents.
The guide is also a relevant match, but it demonstrates a different source of searchable text. Its instructions are a native Article. The setup notes are an attached file. Finding both together gives the reader a route to the information without requiring them to know how it was stored.
What Pro adds to Free search
Free already searches Document titles, descriptions and article content, along with the supported record metadata. That can be enough when your descriptions contain the terms readers use.
Pro adds extracted text from supported files to its search index. A short description can explain what a manual is for without having to repeat every technical term inside it. The matching passage helps readers see the context before choosing the file.
This is keyword search over indexed material. It is not a chatbot that creates an answer, and a matching passage is not a substitute for reading the relevant instructions.
Check your file formats first
The example uses TXT. The built-in extraction paths also cover supported text formats and supported DOCX, ODT, PPTX and XLSX content. Office/OpenDocument extraction depends on the archive content being readable and the server’s required archive support being available. Extraction is bounded for safety; it is not a promise to read every embedded object or every element in a workbook.
Built-in PDF search and OCR are not included. A scanned image needs text recognition, which is a separate capability. If most of your collection is made up of PDFs or scans, check the current supported-provider requirements before choosing a workflow. This TXT demonstration does not establish PDF or OCR support.
A public external link is not automatically a locally readable file. Do not assume that adding a URL causes DocToucan to download and index all of its contents.
For installation and setup, follow the DocToucan Pro guide. The search index reference explains the available fields and diagnostics.
Check the index when a result is missing
Pro’s DocToucan search index screen distinguishes extracted text, metadata-only records, stale or missing entries and failures. That distinction matters: a Document can still be discoverable by its title even when its file text has not been extracted.
If an expected word is missing, first confirm that it appears in a supported, readable source file. Check the index state before rewriting the description to hide the problem. The Rebuild index action processes Documents in bounded background batches; let it finish before judging the updated results.
Test a small set of terms your readers would genuinely use. Include a product name, a word found only inside a supported file and a term that should have no matches. These checks tell you more about the collection than a broad claim that everything is searchable.
Keep search and access as separate decisions
Searching a public library does not make a file private. Public Media Library URLs remain public. If a resource needs restricted delivery, use an appropriate enforced storage and access workflow; do not rely on removing it from a listing.
