A quasi-experimental design was used in this study. Four classes students were assigned to experimental and control group. Analysis of variance (ANOVA) was used to detect significant difference between two groups and Chi-square test was used to examine the changes of keywords utilization. The result of the study were: In regard to the performance of the use of keywords strategy, analysis of Chi-square test showed that there were group differences. The rate of using sentences as keywords strategy of experimental group has reduced from 70% to 20.8%. Phrases strategy, focus changing strategy, Boolean strategy, and using Boolean and focus changing strategy simultaneously accounted for about 31.3%, 4.7%, 30.7% and 12.5% respectively of strategy use. The average upload rate of question searching has risen from 72.79% to 87.9（improving rate 15.11%）. Results indicated that 90﹪students in the experimental group could find the answer and upload it in time. The result of the independent one-way analysis of covariance showed that searching strategy instruction has a significant effect on performance of answering question on posttest. With regard to the performance of unfixed words answer of questions, analysis of independent one-way covariance revealed that a significant effect of searching strategy instruction.
