How do changes in search terms affect search results?

Changing search terms may affect which webpages appear, how they rank, and how the system interprets the question—but adding a word does not necessarily make results more accurate. Historical examples show differences after words were added, reordered, or changed between singular and plural forms. Terms from other languages may also be misinterpreted. When reading results, distinguish ordinary queries from those that use special operators. Results can also stray from the question even when the user has not changed the wording.

Adding or reordering words does more than just narrow results in some cases

A 2004 Search Engine Journal article documented three types of differences:

• Adding a related word: In the example, Google searches for “freeware” and “freeware software” produced results with only 25% overlap.
• Changing word order: The article described substantial ranking differences between Yahoo searches for “dedicated hosting” and “hosting dedicated.”
• Switching between singular and plural forms: At the time, Google searches for “business” and “businesses” were observed to return noticeably different links.

These examples show that similar wording does not mean identical results; adding words does not necessarily just remove a few entries from the original results. However, these were specific observations from 2004. The 25% overlap figure cannot be applied to searches today, nor is there any guarantee that these queries still produce the same differences.

Transliterations and local terms may not be recognized accurately

A 2025 awoo article summarizing a live Q&A noted that search systems do not always recognize non-English terms accurately in English-language queries. For example, the internationally familiar “pad thai” may still return relevant results with a slight misspelling. If the less familiar “kao pad rod fai” is misspelled, the system may need to guess what the user means and offer suggestions. The article also noted that the system sometimes cannot distinguish between “tangbao” and “xiaolongbao.” These examples, relayed by the article, do not guarantee accurate recognition across all languages.

Still, off-topic results do not necessarily mean the input was wrong. In November 2026, Search Engine Journal reported an observation by Nozzle: in one search for “easy strawberry jam,” the AI Overview still provided a jam recipe, but the organic search results showed content related to “easy,” including the television series of that name. This was a specific anomaly and does not mean that search systems generally drop words from multiword queries.

With site:, check whether other search terms are included

Google’s developer documentation explicitly states that results for “site:example.com” without any additional query terms are not ranked. The shortest URL usually appears first, while the rest appear in a fairly random order. This order should therefore not be treated as ordinary keyword rankings.

According to the documentation, adding “lemon” lets you check which URLs on that website can appear in search results for that term. However, site: does not guarantee that all indexed URLs will be listed, so the number of results alone cannot establish how completely a website has been indexed.
