Instructions

Software Usage Instructions

Set keywords: Enter the keywords to count line by line in the “Keyword List”; in regular expression mode, enter one expression per line.
Select a matching method:
- Normal match: Matches characters based on the entered content, suitable for Chinese words and fixed phrases.
- Whole-word match: Suitable for English and numeric terms, reducing false matches when contained within longer words.
- Regular expression: Suitable for counting patterned content such as IDs, dates, and formatted codes.
Configure counting parameters: Enable case sensitivity, overlapping counts, whitespace merging, line-break hyphen merging, hit line counts, and PDF page-by-page counting as needed.
Set snippets and page numbers: Set the number of hit snippets, snippet length, and the PDF start and end pages; entering 0 for the end page means counting to the last page of the document.
Add content: You can paste text or select files such as PDF, DOCX, PPTX, XLSX, TXT, Markdown, HTML, CSV, JSON, and SRT. Multiple files will all be processed, and the interface displays only the first 20.
Save settings: Click “Save Settings” to keep the current keywords, matching method, page range, and export format for future use.
Start counting: After entering the “Count & Download” step, click “Start Counting” and wait for processing to finish to view keyword occurrences, hit line counts, PDF page-by-page results, and hit snippets.
Download results: For a single content item, you can download a TXT, CSV, or JSON report; batch files will generate a ZIP containing the report for each file and an optional summary CSV. If result file names are duplicated, numbers will be appended automatically to distinguish them.

FAQ

A: Common formats such as PDF, DOCX, PPTX, XLSX, TXT, Markdown, HTML, CSV, JSON, and SRT are supported. When batch processing, you can select files in different formats together.

A: Normal match counts characters directly; whole-word match is suitable for English or numeric terms and prevents matching cat in category; regular expression is suitable for patterned content such as IDs, dates, and order numbers, for example INV-\d+.

A: Common reasons include differences between PDF text extraction order and layout order, keywords being split by line breaks or spaces, and English words being divided by line-break hyphens. Try enabling Merge whitespace characters and Merge line-break hyphens, and check the context through the matched snippets.

A: Enter the start page and end page under “PDF Pages”. Enter 0 for the end page to count through the last page of the document; the start page cannot be greater than the end page.

A: When multiple result files have the same name, the system appends numbers such as _2, _3 to the file name to prevent results from overwriting each other.

A: Try narrowing the PDF page range, reducing the number of matched snippets, or processing many files in batches. Regular expressions should also avoid overly complex backtracking patterns.
