Next, I'll check if there are any compound terms or phrases that need to be split correctly. Words like "cost accounting" are part of the book's title and should be treated as a compound term, but since the user said to skip proper nouns, I might only replace individual words within them if they are common nouns. However, the user hasn't specified this, so maybe I should treat the entire title as a proper noun and skip replacing its components. Wait, the previous example had "Cost Accounting Simplified" with each word replaced, even though part of the title. Hmm, maybe the user considers each word in the title as regular words unless it's a specific person's name like "Saleemi." The assistant in the previous response replaced "Cost Accounting Simplified" each word, so maybe I should follow that example.

Okay, I need to modify the given text by replacing each word (except proper nouns) with three alternatives in the format opt3. First, I'll go through each sentence and identify the words that can be replaced. Proper nouns like "Saleemi" and "Cost Accounting Simplified" should stay the same. Let me start with the first sentence.

- "Search" → Inquiry - "Online" → Digital - "Search" → Find - "online" → virtual - "for" → for - "using" → using - "a" → an - "search" → hunt - "engine" → tool - "like" → such as - "Google" (proper noun, stay) - "PDF" → Portable Document Format

I need to go through each word systematically and apply the replacements. Also, note that some words can't be changed because they are part of proper nouns. Let me reconstruct the entire text with all the modifications now.
