Finding Text

Basic Find

Ctrl+F opens the Find bar.

  1. Type your search term.
  2. Enter or the ▶ button jumps to the next match.
  3. Shift+Enter or ◀ goes to the previous match.
  4. Esc closes the bar.

Matches are highlighted in the page. The status bar shows match N of M.

Find Options

Open the Find bar's options panel for:

OptionEffect
Match caseCase-sensitive search
Whole wordMatch only whole words (not substrings)
RegexInterpret the query as a regular expression
Search scopeCurrent page / current document / all open tabs
Include annotationsAlso search inside sticky notes and text box text

Find and Replace

Ctrl+H opens the replace dialog. Works on:

  • Page text (where selectable / OCR'd).
  • Annotation text (sticky notes, text boxes, text callouts).

Page text replacement writes changes back to the PDF content stream. Annotation text replacement updates the relevant annotation's Contents property.

Tip

Warning — Replacing text in a native PDF's content stream is complex and may not preserve exact formatting (font, kerning, line breaks). Always review after replace.

Highlight All Matches

The Find bar has a Highlight All toggle. When on, every match on the current page is highlighted with a yellow overlay until you close Find.

Search Limitations

  • Image-only pages without OCR — search returns no results. Run OCR first (see 06.1).
  • Encoded / non-Unicode text — some older PDFs use custom encodings that don't index properly. Spark falls back to glyph-level search; accuracy depends on the PDF.
  • Vertical / rotated text — search works but highlights may appear on the rotated bounds.

Searching Annotations

The Comments side panel has its own search box:

  1. Open the Comments panel.
  2. Type in its search field.
  3. Results filter the comment list.
  4. Click a result to jump to the annotation.

This searches:

  • Sticky note bodies.
  • Text box contents.
  • Text callout contents.
  • Stamp labels (if custom).
  • Annotation comments (Properties → Contents).

Go To Page

Ctrl+G — type a page number to jump directly. Not a text search, but often useful alongside Find for navigating long documents.

Tip

Tip — For engineering drawings with scattered text, enable Search scope: current document and combine with Highlight All to see at a glance where a term appears across all pages — great for locating a drawing reference.
